[b]The United States of America:[/b]

The USA was hit hard by the Heavenfall. With the vast majority of the largest cities being coastal, there was devastating damage and unprecedented loss of life from both the initial destruction, as well as the chaos that followed. The government was stretched thin trying to simply deal with the massive number of casualties and deaths, and to try and provide aid to all those that suffered. Millions were left homeless, with all their property and belongings lost. Additionally, huge amounts of infrastructure were destroyed; powerplants, manufacturing, utilities and more were all wrecked beyond repair. 

Even sorting through and making sense of this level of chaos took months, and reconstruction and relocation efforts took even longer. 
The majority of senior government were wiped out during the incident, and the fallout following soured the reputation and opinions of much of the public. 
This was especially the case as less-than scrupulous, compassionate, or socially-minded representatives or members of the government attempted to spin the narrative in order to serve their own interests and ensure their own positions and power. This resulted in a considerable reshuffling and reorganization of political parties and sitting senators and members of the government. 
As a result, the overall culture has reverted to a more liberal and socially-conscious one overall along both sides of the political fence. The current senate and government is one that is more focused cultural, social and societal concerns, unity and co-operation, than on personal or corporate economic or financial gain and prosperity.
This resulted in a huge cultural division, as in the wake of the disaster, many of the more extremist sections of the population emerged in force, taking the name the White American Nationalist Coalition. 
After an unsuccessful attempt to wrest control of several southern states under arms and supported by rebellious elements of the national guard and armed forces, they instead fled the country and regouped in South America.

The demand and sheer need for medical services and assistance during the fallout from the Heavenfall also rendered the idea of private medical services laughably unworkable and unethical, and as a result the private medical industry and health insurance collapsed and were replaced with a hastily organised programe of government-provided medical care, the exact details of which are still to this day being sorted out and debated, as with much of the current US policies between hardline traditionalists and the newer, more moderate and liberal representatives.

Overall, the USA has lost some of its international power and influence, with the loss of so much economic and material power, along with the loss of a large portion of its' military might and capability. The rebuilding of military forces has been focused on modernisation and the pursuit of a more mobile, quick-reaction force. 
The need for rapid reconstruction and restoration of economic and manufacturing power has resulted in the rapid takeover and amalgamation of many companies and corporations into larger ones that had managed to weather and survive the disasters, and their economic might and presence has allowed them to exert influence and control over the government, though many have moved from their one-time headquarters in the USA in favour of countries with less restrictive laws and policies, allowing for unrestricted and uncontrolled development and research. 
Much of the US population has relocated to the inner heartland of the country, while rebuilding of the coastal regions continues, albeit slowly. This has resulted in overpopulation of some cities and regions, with infrastructure and public services struggling to cope as more people than they were designed, staffed, or budgeted for are now depending on them. There is a demand and competition for resources. The divide between the wealthy and the poorer has become more marked, and many current government policies and initiatives are heavily focused on addressing this balance.  
On the upside, employment is plentiful as reconstruction continues, with both blue-collar and white-collar jobs being plentiful. However, the dissatisfaction and frustration many people feel has resulted in a rising crime rate, and the institution of several unpopular policies for the enforcement of law and order, especially in these heavily populated regions. 

The Southern USA, especially where it borders Mexico and the Gulf of Mexico have been subject to a lot of unrest and ongoing low-intensity conflicts along the borders between US troops and militarised cartel and other forces. Often they have little interest in seizing and occupying territory, but only ensuring the continued flow of their product or their ability to act without challenge or consequences in distributing their product and receiving payment to keep their enterprise going, and the use of military-grade firepower, equipment and tactics to enable this. 

Alaska and Hawaii still remain under US governance and control, but due to their (relative) remoteness, especially during the period of the Heavenfall and the reconstruction, often are at odds with the central government of the USA and exhibit a lot more independence. They primarily put the interests of their own populations first, sometimes causing clashes of policy and ideology within the government, and have acted with more autonomy on various occasions, much to the frustration and anger of the central US Government.

The USA does still maintain it's nuclear arsenal, as well as an extensive surveillance and intelligence apparatus and a substantial naval fleet and air force giving it a considerable presence on the global stage, despite its' reduced economic, political and military influence. As such it is still an important member of the N/UN, and has a considerable say in the direction and implementation of N/UN policies and strategy.

Canada was surprisingly lucky with how the outcome of the Heavenfall affected it. With it's population centers and population overall being concentrated in mostly inland areas and in the southern area of the country, the more sparsely populated northern territories were hit more heavily by the actual impacts. While this still caused considerable devastation due to the geological upheaval and resulting Long Winter, the rebuilding was (comparatively) easier, and industry and infrastructure was somewhat less heavily impacted that that of other countries. 

The loss of life was still devastating, as were the ecological effects, but the country and government managed to retain control and provide relief to citizens, as well as allies and the neighbouring North America following the disaster. 
Canada has since become important for its' abundant natural resources and its' manufacturing and industrial base that managed to survive. However, these same resources are stretched thin and overworked, leading to a high demand for workers and a desire to build more factories and industrial plants, something that is a matter of intense debate and contention, especially with the possibility of allowing more corporate control and interests into the country. 

Canada has also accepted many refugees into its' borders following the disaster of the Heavenfall, especially with the need for a workforce to manage the increased demand for manufacturing and production. This has lead to some cultural clashes and unrest between various sectors of the population, and an increase in criminal activity as the unrest and tension has grown. 

Canada's military has always been one that was professional, competent and adequately equipped for the duties it undertook, albeit somewhat less-than modern in many respects, or by comparison to those it considered allies. While it survived the Heavenfall mostly intact, the losses of equipment, manpower and materiel have resulted in a program of intense modernisation and re-equipping to enable a modern, capable fighting force that is ready and more-than able to respond to the obligations it has as an important member of the N/UN. 

Canada is considered on the whole to be one of the better and more pleasant places to live in the post-Heavenfall world, despite it's issues internally, and is seen as one of the more stable regions and nations.
