I don’t think that South America is seeing leftism bloom because of Trump, I think they’re seeing it because of the work of south Americans. I think the south Americans work was easier under Trump - As you yourself said “the decline of Empire”. He was much worse at administering the American empire, which accelerated it’s collapse.

Trump killing Soleimani was wrong and I don’t think I’ve at any point said anything to the contrary? It was also something that wasn’t widely supported, which fucked up soft power further. The war didn’t escalate because of Iran, and Iran was able to keep tensions low because Trump was an incompetent buffoon incapable of whipping the rest of the west and the media in line.
