Western Europe
Note: 'Europe' refers to the geographical region in this instance, rather than the European Union specifically.
Western Europe is geologically relatively stable; there are very few active volcanoes and fault lines in the region, and historically it has not been especially prone to large or regular earthquakes or tectonic events. Of course, the Heavenfall was an exception and the main site of impact was on the Eastern part of the Eurasian plate, which sent reverberations across it creating massive destruction. Buildings were devastated, there were massive landslips and avalanches, tunnels and bridges collapsed and massive tidal waves devastated the many coastal cities and regions. In addition, the subsequent rise in sea levels lead to devastation of the many coastal population centers and important areas.
The British Isles (Including the Republic of Ireland, Channel Islands, Isle of Man and Shetland Islands)
The UK - that is, England, Wales, Scotland and Northern Ireland, along with the Shetland Islands, Isle of Man and Channel Islands - did not weather the destruction wrought by the Heavenfall well. With so many large settlements in coastal areas, including London; the Nation's capital, this lead to huge loss of life, as well as the loss of a vast amount of historically and culturally significant buildings, artefacts and objects, as well as significant industrial, government, communication, military and utility infrastructure.
The following years were a terrible struggle as the crippled countries tried to provide for their battered populations. The remains of the govenment, the back-benchers and local MPs, had to weld themselves into a functioning parliament and rapidly to be able to cope with the cascade of demands placed on them by the vast number of relocated people flooding into the cities more inland, feeding them, accommodating them, and meeting their medical demands.
It was a gruelling and harsh few years, but slowly and surely the British Isles turned around. Like every country across the world, they were heavily affected by the Heavenfall disaster, and it was inescapable without change to the country.
With the reducation and scarcity of resources, becoming a member of the N/UN for the mutual aid, relief, and protection was seen as an overall benefit, and the UK and ROI both signed on to be members, committing their armed forces to the international organization. The UK still has control and access to it's nuclear weapons aboard ballistic missile submarines, and remains a nuclear power, despite the reduction in its' wealth and power.
Several of the overseas dependencies of the United Kingdom have been lost or taken during the Heavenfall and afterward, with many occupied by surrounding nations or regional powers. The UK government has expressed interest in retaking and resuming governance of these territories, especially after the populations have spoken out against the occupations and pleaded for assistance, but there are currently no actions planned, due to the reduced military capabilities of the UK. N/UN strategies and actions are being drawn up to accommodate all member nations needs, but there are - understandably - numerous interests from many nations that are conflicting in priorities. The Falkland Islands in particular were once against seized by Argentina, and a second Falklands War was fought during 2010, this time involving UK strikes on the Argentine mainland to cripple their ability to stage such an attack again.
France
Paris was thankfully spared much of the devastation, and France as a whole managed to come through more intact than many other European countries, leaving it in comparatively good standing and with a relatively powerful stance in the following years, despite devastation along its' coastlines.
The struggles for France came not from the destruction - though, it was not insignificant - nor from the loss of life and ability to restore and supply order and working services, but instead from internal dissention and rebellion. There had already been an undercurrent of dissidence brewing in the country between ethnic, religious, ideological and political groups, and the chaos of the Heavenfall and the post-disaster period, where the government, along with Law Enforcement and military agencies were at their weakest was seen as an opportunity. Massive riots broke out along with numerous violent clashes as the government attempted to retain control. There were many brutal and violent losses of life on all sides, which in turn spurred more action by those affected, especially speaking out against the governments' perceived heavy-handed responses.
Ultimately, once order was restore, elections were held, and a new government elected that is somewhat more independent and nationalist than earlier ones had been, and has been noted in recent years for actions, policies and decisions that have been much more 'France First' and considered to be on the authoritarian side.
France has transition from UN membership to N/UN membership, but is notably often an outspoken voice in discussion, and one of dissention when it comes to policy.
Frances' overseas territories were lost during the Heavenfall and the following chaos and violence, and the French government has expressed interest in retaking control of them, but has not yet committed to military action to do so.
France also conceded a small amount of territory and land when Euskadi, described below, was formed.
Germany and Austria
Germany was divided into East and West up until the Cold War ended as a result of the Heavenfall. Prior to this, there were a handful of small skirmishes, though none ever amounted to full-scale conflict. These were often over border incidents and caused by overzealous application and enforcement of rules.
Berlin had been the hotspot of espionage and intelligence activities by both sides, and there were a handful of notorious and diplomatically embarassing intelligence incidents where operatives of one side or the other were exposed or caught.
The Berlin wall itself collapsed in numerous places during the Heavenfall and in its' aftermath. In the following chaos, there were many incidents of violence as military and law enforcement personnel with no clear orders struggled to uphold or interpret order, until the government on both sides of the former border reached agreement, especially after the USSR rapidly dissolved and fell apart in the following days and months.
Reunification of Germany from the East and West happened relatively quickly after this. Borders were dismantled, along with the agencies that had enforced them, and the various government agencies, branches and departments were merged, along with military forces. Much of this was done as quickly as possible out of practical need, due to the losses of life and destruction following the disaster, but there were still many issues and problems that arose with the necessary reshuffling of personnel and their positions and appointments, and resolving all manner of administrative and practical issues.
The interior of the country and much of it's industry was relatively unaffected by the disaster, and as such managed to maintain its' economic and manufacturing power, along with - after the reshuffling and reorganization - a relatively stable, secure, and capable military that is equipped with a mixture of former Soviet and Western equipment, though much of the former Soviet gear and vehicles are being replaced with indigenously developed and built equipment, thanks to the aforementioned industry coming through the Heavenfall disaster relatively intact.
Germany holds a seat on the N/UN council and contributes considerable forces and resources to the international organization.
Austria weathered the Heavenfall with remarkably little impact. As a landlocked country it had no shorelines to be flooded or destroyed, and resting in a geologically stable area, the earthquakes had little effect, though there was naturally some destruction and loss of life, and more followed in the shortages of food and resources due to the 'long night' that followed.
Nonetheless, the country survived with much of its' infrastructure intact and was able to rebuild relatively quickly, and provided aid to its' neigbours and other allies where possible in their reconstruction and relief efforts. There were some internal debates and disagreements about how much aid should be sent or rendered externally, and this did cause a rise in nationalist sentiment from some sections of the population and government, but this did not amount to any great change or movement.
Austria remains a stable and peaceful nation, and as such is home to many businesses and other enterprises. Austria is not a contributing member to the N/UN but has numerous mutual aid and defence agreements, and is a peaceful ally and trade partner with them, and several other nations and groups worldwide.
Austria has a modern and well-equipped, well-trained military that has participated in many mutual defence exercises and deployments with N/UN and other allied forces.
Belgium, the Netherlands and Luxembourg
The Benelux countries were greatly affected by the tidal impacts of the Heavenfall, due to their low-lying geography. With a lot of reclaimed land protected only by dams and sea barriers, the massive tidal activity and following rising sea levels could not be countered quickly, or efficiently, enough to save those areas. As such, many lives were lost, along with large areas of farming and agricultural land and many built-up areas, including several entire villages, towns, and even cities.
Disaster relief was a priority, and it took years for the situation to stabilise. Hundreds of thousands of people were displaced, and the strain on resources and infrastructure was great as a result
Having always had close relations and a great deal of shared history and ethnicity, the monumental decision was made to merge the territories of Luxembourg, The Netherlands and Belgium into one, adopting the name Benelux, as had been used for their longstanding co-operative agreements on other matters.
In essence, the three countries retained their national identities and individual capitals, cultural heritage and other important national identities, but shared a national government, laws, economic, defense, and other important governing policies, much like the United Kingdom.
The new state was governed by a parliament of officials from each country, with an elected Prime Minister. Brussels became the national capital as it has long been recognised as an important international city, and also because it survived the Heavenfall more intact than many other cities in the region.
Benelux is part of the N/UN, and is starting to contribute more to the international organisation as it begins to become more and more capable and better organised and established.
Spain, Portugal, Andorra and Euskadi
Spain and Portugal were both affected heavily by the Heavenfall, with many of Portguals key cities ravaged by the tidal and geological upheaval. Many of Spain's larger coastal settlements were likewise devastated, and much of the population moving inland in search of shelter, aid, and relief. Portugal's government turned to assistance from their neighbour, as their own relief efforts were massively strained.
Both nations suffered extensive losses of life during this period, and their infrastructure and services were terribly strained due to the extra demands.
As a result of this, enforcement of government policies, laws, and treaties was at an all time low, due to the vast strain and demand on surviving resources. The Canary Islands and Azores, heavily damaged by the tidal activity and rising sea levels were left mostly to fend for themselves, and as a result suffered extensive losses of life, as well as rising criminal activity, that left them something of a haven for criminal activity, a situation that was only resolved many years later when the Spanish armed forces were able to retake the islands, though they still bear the scars of such activity, and many illegal activities are still operated out of the islands, and they are still home to many unscrupulous individuals.
In the North-East of Spain, the disruption in law enforcement and governance allowed an opportunity for the more extreme elements of Basque sepratism to rear their heads and become organised. Over the years following the Heavenfall, they managed to carve out an independent territory for themselves, and through canny deals with various independent contractors and organisations, enforced their borders and independence. The newly-formed NCAA, along with other unaligned nations recognised the newly formed Basque nation of Euskadi, and it became home to the large and well-equipped PMC organisation Nightwatch, who also act as the de facto security forces for Euskadi.
Andorra remained independent, and was mostly unaffected by the Heavenfall other than it causing a considerable amount of property damage, fires, and other such civil disruptions and destruction. The country itself remains intact and healthy, though concerned about Euskadi being so close and the disruptive presence the new nation causes, compared to its' N/UN aligned neigbouring territories.
Spain, Portugal and Andorra are all N/UN member states, and while Spain and especially Portugal are still recovering to some degree, both contribute to the N/UN's armed forces, as well as participating in policy decisions and other programmes and important functions of the international organization.
Italy, The Vatican, Monaco, Lichtenstein and Switzerland
Italy suffered extensive coastal damage, with coastal cities and settlements, including several important ports and naval facilities being heavily damaged, if not by the initial tides, by the subsequent rising water levels. Venice in particular was all-but destroyed, along with the islands in the lagoon along with it. Many mountainous regions of the country suffered extensive damage due to landslips and falling debris, along with avalanches and other similar natural disasters. San Marino was especially devastated, being a mountainous and hilly place, and one with little in the way of its' own emergency services, and was supplied with relief and aid by the Italian government.
Many of Italy's major cities were - fortunately - somewhat inland and located in less mountainous regions, and while suffering damage from the geological upheavals and subsequent fires, floods and other damage, managed to weather the overall damage and were repairable and able to be reconstructed.
As with other countries and regions, there were large numbers of displaced persons, as well as huge amounts of injured, and later sick, people that needed aid and shelter, and this caused a great deal of strain for the countries government, emergency services, medical services and infrastructure, along with the strain on resources due to the extensive rebuilding and reconstruction efforts, many of which are still ongoing.
Sardinia, Corsica and Sicily were all also greatly affected and required a lot of reconstruction efforts, as well as a great deal of aid, as the majority of settlements on these islands were coastal and the loss of life was great as a result, much the same as Malta, to the south, which while an independent nation had long been in agreement with Italy to provide aid, defense and other critical services when the need arose. Much of Malta's coastline was heavily damaged, resulting the destruction of many population, industrial and commercial centers of importance and significant loss of life and property. However, the rebuilding commenced quickly, along with extensive programs of modernisation and development, welcoming in new business oppotunities and turning the island nation into a destination for white-collar financial, technical, and other such companies and institutions.
Both Malta and Italy became members of the N/UN with Italy having a significant commitment in armed forces to the international agency. Malta was an early and immediate recipient of the N/UN's commitment for protection via the use of the vetted and authorised PMC program and acts, with the small, but capable and well-trained, PMC of Vanguard Security stationed there for 18 months during the period of greatest vulnerability.
To the North and West, the tiny nation of Lichtenstein weathered the Heavenfall with little damage or impact, coming through almost entirely intact and with little loss of life, property or industry. This stability allowed them to maintain their position as a haven for wealth and economic power, especially in conjunction with the neighbouring Switzerland to the west, which was similarly unaffected or at least, weathered the damage due to a long history of building shelters and fortifications against disaster. With so much economic wealth and power held in such stability, as well as having remained officially neutral throughout the Cold War, Switzerland and Lichtenstein became monetary and financial centers for the resurgent world order, and among the richest countries, despite their small size.
Neither country is a member of the N/UN, but are peaceful, allied nations and regularly engage in talks, debates and summits regarding issues that affect global well-being and are of importance and relevance.
Monaco, bordering Italy and France to the West and North respectively, did not fair well. Being an entirely coastal country and extremely small, it suffered terrible destruction and loss of life, the iconic and famous riviera almost completely destroyed from the Heavenfalls' impact. There were survivors, of course; but the country was affected heavily. The added impact from this was that the economic power and the people it was tied up in were also devastated and destroyed, leading to something of a noticeable 'drain' on the global population of millionaires. Rebuilding and reinvestment in the country was aided by a policy to invite hi-tech, low-impact industry and business into the country, leading to a disproportionate number of head offices or other important facilities and offices for megacorporations being based in Monaco.
The Scandinavian Alliance
During the Cold War, Sweden maintained its' neutrality from NATO while still being opposed to the Eastern bloc and Soviet Union; though was a covert ally with an 'officially unofficial' understanding that the nation would fight as a NATO ally in the event of any large-scale war.
Norway, Denmark, Iceland and Finland were all member countries of NATO with close ties to NATO nations for defensive and economic purposes. Sweden likewise maintained ties with NATO countries, such as purchasing weapons, equipment, vehicles and more from them and co-operating in exercises along with mutual treaties.
Over the course of the Cold War into the 1990's and early 2000's, some of these agreements grew more contentious and distant, especially after several incidents of hostile encounters between Soviet personnel and units infringing on borders of Finland, Norway, Iceland and Sweden. Few of these came to much more than a short exchange of words, and rarely was any fire exchanged. However, the lackluster response from NATO allies to these incidents lead to closer ties forming between the Scandinavian nations, and increased policies and acts of mutual co-operation and signing of several agreements and treaties.
This only increased after the Heavenfall, as the damage to these countries was extensive due to their extensive coastlines, mountainous geography, and extensive damage from other natural disasters such as avalanches, flooding, and other such incidents. With many remote regions and communities, the treaties signed for mutual aid were more beneficial than ever, and the ties between the Scandinavian nations strengthened into a sense of shared fate and destiny, especially so in the face of having weathered the disaster.
The nations of Denmark, Sweden, Finland, Norway and Iceland, as well as their depdendent territories such as Greenland and the Faroe Islands, formed an Alliance as a United entity. They collaborated on matters of law, governance, defence, economics and other such mutually beneficial matters. While remaining separate countries, those residing within them enjoyed unrestricted travel between the member nations, along with civil rights, laws, freedoms and other such standards being unified.
The unified state is known as The Scandinavian Alliance, and is governed by a council of elected representatives from the member nations, with an elected President.
The Scandinavian Alliance is not a member state of the N/UN, but maintain cordial relations with the global power, and has various mutual treaties and agreements with them, but maintain a strong posture of individual freedom to act and implement its' policies as it sees fit. Nonetheless, the Scandinavian Alliance does operate and trade numerous weapon systems, vehicles, equipment that is used by other world powers, as well as exporting its' own worldwide.
There has been a building friction between the Scandinavian Alliance and the N/UN, due to expansion from the Eastern borders of Finland where it meets the former USSR, as TSA forces have begun to expand, in response to requests for aid and security from communities in the area that have been left with little to no civilised or modern utilities and standards of living due to the breakdown of the Soviet government and its' infrastructure, as well as the random and frequent acts of predatory violence and brutality by the would-be dictators and rulers that were once military officers, government officials, or other persons in positions of power and influence. The N/UN is left in an awkward position, while not condoning the unilateral action, they are also unable to condemn it, as it aligns with their own goals and aims, and it has been a tense diplomatic issue since.
