Who cares what "org" the countries belong to? Call them "Europe", EU is simpler to type..
You obviously got no clue as to the required association to NATO membership, in order to become an EU member.
They need to pay the fuck up before the US adds any more taxpayer dollars.
The European NATO members do NOT require the USA to "help/defend" them - especially not since 1990, therefore pay the USA for WHAT? The European NATO's own annual defense spending's add up to around US$ 450 Billion.
NATO is an essential power-tool for the USA, to maintain it's imperialistic and hegemonic global policy.
The USA became financially overstretched since 1990 due to fucking up Iraq, Afghanistan and a dozen other countries - total around US$7.5 trillion. (around 15 times it's annual defense budget at average) If e.g. Germany would have spend US$ 650 billion since 1990 to make war - they would also be telling the EU to pay the fuck up.
When Britain "defended" it's Empire e.g. Malvina's/Falklands - they also told the EU to pay the Fuck up - and the EU told them Go F Yourself.
Since China's rise, especially from 2000 onward - far more potent then the USSR ever was - the respective US governments have realized their financial shortcomings in regards to controlling the Globe.
Thus using false accusations and yapping about democracy in order to get "an Asian/Pacific alliance" to step in financially. However unlike the EU or the European NATO there is no such united organization in Asia/Pacific, neither that in it's potential financially/militarily capabilities would be comparable to the EU. There is only Japan - the rest is mediocre compared to e.g. Germany, Britain, France and Italy - not to mention the entire EU. S-Korea got it's own existing worries and Australia is 4000mls away. and India has it's own existing issues with everyone of its neighbors.
You better keep Ukraine whole before Putin takes a bite somewhere else.
The Russian Federation unlike the USA and it's NATO serfs, hasn't taken any "Bite" since 1990. And with an autocratic person like Putin coming into play - Russia want's to make sure that the US/NATO stops biting/scratching and chewing up their neighborhood. - and China has the same policy.
Haven't St. Donald & senile Biden informed you about all this?
