The amount to keep this going or finding a viable solution seems like it would need to be in the trillions.
Not even sure why the U.S. is a part of NATO.
Instead of ****ing them over, maybe we should let them run their own lives the way they want.
World War 2 and Soviet Union are the reasons.
NATO was initially concepted based off the failure of the Western Allies to coordinate a method to stop Germany in 1940.
History of NATO - Wikipedia
The Western Defense Union was initially setup for France, UK, and the three Benelux countries to plan better defensive strategy. USA agreed to join and was invited plus USA brought friends: Canada, Denmark, Norway, Italy, Iceland, and Portugal.
This is also when the Alliance became more Soviet focused and they eventually invited West Germany (who became Germany), Greece, Turkey, and Spain eventually joined.
Than in 1991, it grew to include a lot of Eastern Europe members that are now in today.
Alliance has kept Europe from a 1939-1945 type World War. To me, the problem with the Alliance is not integrating Russia into it. You have all the major European nations except one in it so it looks like the exclusive club is pretty much an Anti-Russia league which has been what happened.
I don't really care about defense expenditures as a lot of these nations are in it to give access to their territory for bases IMO. I really think only the major countries are the ones we are pushing: Canada, UK, France, Germany, and Italy are the big ones. Poland as well but I am fairly confident that Poland puts up the numbers. Sweden is another new player but from the data, Sweden meets 2% requirement.
Do we care whether Iceland, Luxembourg, Portugal, Netherlands, or Denmark meet the 2% threshold? These nations are so small, it would matter anyways.
