Yes. NATO is an arm of the Pentagon. It exists to project American power into Europe. So it's appropriate that the U.S. funds it.
I don't think we should be in NATO. But I don't blame anyone else for not wanting to fund it.
As for the UN, it's a platform for Third World financial demands, for American LGBT promotion, and for Euro-American climate change projects.
No reason why any nation should fund it, so there is no "fair share." But if any nation is dumb enough to fund the UN, that's on them.
We shouldn't fund NATO or the UN. And if some other nation refuses to pay their "fair share" they have my compliments.
Yes, NATO largely ended war in what was the most violent place on earth.
Romans, Parisians et al have been able to live to almost 80yrs old without being warred on once in their lives for the first time in ages. They simultaneously decimated their own military spending.
I don’t think we should be in NATO. Victimization lasts forever, accomplishments like ending war in Northern and Western Europe can be wiped out by some rainbow flags and likewise nonsense.
