Name of Nation: Forbund Skanska (Scandinavian confederation)

Territories: Sweden, Norway (and all overseas possessions), Denmark (and all overseas possessions) Finland, Shetland Islands, Orkney, Iceland, Greenland, Estonia, Lithuania, Latvia, for a population of 60 million all told. 

Government Type: Constitutional Monarchy (Sweden), Confederation (The confederation, duh). There is a king whose powers are increased, however the people still have constitutional protection, and the Riksdag still exercises oversight over the king and exercises all domestic policy. Interconfederate relations between countries are to be controlled by the central government, as is trade with foreign nations. Each nation has its own government that determines domestic politics, however the Forbundsdag (dominated by Sweden as it is the most populous) determines foreign policy, military spending, and aforementioned interconfederate relations. 

Military: The sheer impossibility of invading Sweden and Norway effectively over northern Scandinavia in sufficient numbers and the limited manpower in the confederation hinted strongly that they should prioritize the air force. Each country effectively specializes in one element of the national defense. The Finns and Balts specialize in the army, Norway and Denmark in the navy, Sweden in the Air Force. Nationally, the air force is the strongest, the army second, and the navy third (however nuclear missile bearing submarines are nationally priotized). The navy prioritizes submarines, missle cruisers and minelayers as means of sea denial. 

Economy: Export of timber, iron, high-tech goods. With the advent of 3D printing, which the Federation has wholeheartedly accepted, manufacturing can be done on a much broader scale, and it had the benefit of freeing up men for military service.

Foreign Policy: The Scandinavian Confederation is fully aware of the difficulty posed by war with its neighbors Russia and Germany, both of which have nearly three times the population. So instead, it endeavors to play the two off each other, and convince both that an invasion would be so tremendously costly as to be not worth it. The Scandinavian Confederation also possesses nuclear weapons to that end. 

History: About the year 2014, Scandinavia and the Baltic states as a whole recognized their demographic crisis and took drastic steps. They each instituted drastic policies to raise birth rates, and in concert with new feelings of national pride and optimism for the future as free market policies made everyone wealthy, quickly raised fertility rates to an astonishing four births per woman. During the war, the withdrawal of the US from NATO forced the Baltics and Nordics to look to more practical ends for their defense. The month after the US withdrew from NATO, the Baltic states, Iceland and the Nordics created the Scandinavian Confederation. Finland was convinced to abandon traditional neutrality and join. Orkney and the Shetland Islands seceded from the UK to join as well. The Confederation, per Sweden and Finland’s traditions, maintained hard and fast neutrality, and was soon inundated by refugees.
