But also, a bigger alliance creates a larger amount of territory to defend. For example if the US were to leave NATO, they miss out on all the benefits that European NATO members provide, but also would not need to defend Europe, which is where any war involving NATO members is likely to happen. It seems to me that the US gains very little from being in NATO.
>it seems to me that the US gains very little from being in NATO. So far Europeans died in USA conflicts around the world , how many conflicts did Europe start and USA had to get involved so far ? From me a Romanian, feels very shitty that our soldiers died in Iraq and Afghanistan for America but now if we will need help Trumpists will not help back.
Setting aside for a moment the rather large conflict that ended in 1945 - if you're in your late 20s or older, both Libya and Kosovo happened within your lifetime and meet your criteria.
