Agreed, the damage to the US as a country is insane - isolationism, as a concept, has historically led countries into literal dark ages. And that was BEFORE global politics became instantaneous.

America's economy and military is so strong that the short term effect on other nations is massive, but if those other nations are still working cooperatively while the US "opts out", it will not take long at all for the US to be replaced as the world's #1 - both economically and, in turn, military. They can easily be leapfrogged in both by a united Europe and BRICS. They could legitimately hit the #3 spot, their current actions are absolute madness for the world AND for the US on its own.
