Factions

Countries often agree on one thing as a whole, such as economic deals and whatnot. For easier management, these countries often form factions or, if you want to be more verbose, international organizations. Four major factions exist (not excluding the United Nations for obvious reasons) and the reason for formation varies between them. Although there are some others that are not mentioned as part of the "major four", note that they generally might just be copy and pasted from the real world.

Eurasian Union
The Eurasian Union is an economic and political international organization. It was founded by Caspia and Karelia in 1970 initially to combat any attempt of the Worker's Soviet Socialist Eurasian Union at invading the two countries. It grew over the years after the fall of the WSSEU as the current state it is in.

Members can be found on it's individual page.

MEDITERRA
MEDITERRA (written in all caps in order to sound like an organization) is a military alliance between members that border the Mediterranean Sea, but are not exactly limited to the Sea itself. It is perhaps the strongest force in Europe when it's forces are combined to mount offensives on certain areas. The founding members were Italy and Macedonia.

Coalition of the Americas
The Coalition of the Americas is a political alliance founded by Amazonia. It's members include the vast majority of South America, and is stretching into Central America. The COTA does not have plans to invite the United States into the faction due to major differences, the US is still heading down a path of joining COTA depending on it's diplomatic actions.

East Asian Federal Republics
The East Asian Federal Republics (EAFR) is a military and economic alliance founded by the Federation of the East and the Hainan Federation. It was created to combat Russia's ever-growing strength and rule over the Eurasian continent and seeks to prevent it's total domination. The EAFR and COTA have been long-standing rivals for nearly fourty years ever since the EAFR was founded in 1970.

NATO
The North Atlantic Treaty Organization (NATO) is a military alliance headed by and founded by the United States. It doesn't and does consider itself the "world police", and the majority of members in Europe are part of NATO. Initially, it was made as a result of the Warsaw Pact having been formed, but after the collapse of the WP and the WSSEU as a whole, NATO simply serves as a warning signal for the majority of the world.
