Counterpoint: the US made bank being the enforcer of the rules based order. But being the most wealthy country in the world is apparently not enough. And to be direct, the US was the one rattling russia's cage the past 30 years.. and now it all escalated you cannot just nope out without consequences.
And in regards to money spent.. the us sends weapons.. meaning all the money stays in country, adding to the Pentagon budget for new kit. The EU mostly keeps Ukraine afloat financially.. so they can pay their soldiers etc...
Reunion was the only french territory faaaaaaar away I can name. If you have another desolate rock in a far away ocean that would be better.
