The only reason Russia is invading Ukraine is because they feel threatened by the USA and NATO and they need a buffer for their own defense. If USA left NATO and especially if Russia joined after that then Russia would not feel the need to secure a buffer between NATO and Russia.
China probably would not feel as threatened either if the USA were not as involved in Asia as it is currently. I think the world could actually reach a new level of peace if President Trump would withdraw the USA from NATO and isolate the USA from world politics.
This I can get behind. NATO too. But disengaging from the world completely isnt the right strategy. We need to cooperate and compete honestly on equal footing always with the ideal of America First. You lead by example same as you have peace through strength.
In theory, yes. But as Putin pointed out in the interview with Tucker Carlson, America weaponized our currency and tried to control other nations through it. It worked for decades .. until it didn't. As Putin said, it was a serious mistake.
So now we have to start from scratch on the global stage.
