I keep pointing this out. Europe has over 500 million people and a GDP larger than Americas.
Russia has 145 million people and a GDP that is not even in the top 10 in the world. It spends about 3.5% of GDP on Defense.
Why pray tell, should Europe need Americas help defending itself from Russia?
Well how can we justify hundreds of billions per year on our military if we just give up having enemies to confront?
