There was a lot of forceful diplomacy by the US. Sure, but there was also a lot of actually good diplomacy happening. Calling all of that a thin glove is underselling the good work of a lot people.
The good side of US diplomacy was one of the most positive forces in the world. Trump fully dismantled that. Not just the US aid work, but also the Pax Americana that really limited the scale of war in the world.
There were horrible missteps at the same time. The US wasn’t all good. Maybe it wasn’t even net good. But there was a significant good side, and its dismantling isn’t a small thing in the world.
