Trump is different. That's why I said 'by Trump' and not 'by the USA'. Trump is keen on destroying everything not just Biden's legacy like the CHIPS act or IRA but also USAID, consumer and climate protection, FEMA, education, scientific and medical research, now postal service and FAA. UN and UN institutions like WHO, Unesco, Unicef will be next. I doubt that the republicans would understand why he's doing all that.One thing is certain, the USA "acquiring" them would nullify all such accusations against Russia.
I am surpised you don't see a future for the UN.Like the old League of Nations pre WW2, they have no useful future. All they've ever achieved is to help the USA make endless trouble for the rest of us.
Who run the biggest charitable programs in the wolrd? WFP, WHO, Unicef, Unesco, peace keeping, etc to cite a few. Who else can replace the UN?
BTW, Trump has already u-turned on tariffs.
