How about the cold war?
Erm... that was your war against the Soviet Union. You achieved global political and economic domination, and Europeans helped you with it. If anyone should pay any bills for that, it's the USA (you didn't fight any defensive wars for Europe but Europeans and other NATO allies helped you with your wars of aggression).
the cost of maintaining the US nukes that protect Europe?
How many of them were fired in protection of Europe? So maybe they are not protecting Europe but help keeping Europe within the American sphere of influence?
how about all the NATO expenses the US paid
Did you buy tanks for Poland, or for any other NATO country? Did you give them fighter planes or artillery? Or did they
buy those weapons from you? So what else do you want money for?
In general PolAm, I think it's time to end the US domination over the world. It's time to give up dollar as world's reserve currency and end the obscene wealth of Americans. If an average Chinese consumed as much as an average American, we would need three additional Earths. But you simply cannot appreciate the fact. So maybe, just maybe, it's time for Americans to work as hard for as little as the people of Mexico, Vietnam, Pakistan or Russia do? Perhaps the time when you stretched the anuses of almost the entire world is just coming to its end?
