Is the US orchestrating coup after coup all over the globe a desirable rational actor ?

The reality is that it will take multiple generations for us to get rid politicians who when zoomed out act like teenage boys, and we can argue all we want.

WW1 already demonstrated that "trade keeps peace" can't be counted on, but some people never learn. The argument was made and soundly debunked many years before anybody here was even born.

Yes the difference could be that I am against US hegemony, and all for finally somehow growing up and attempting to avoid a catastrophic, planet annihilating conflict.

That would probably require a different point of view than labelling China as the enemy, or keeping them pre-industrial and poor in order to control them, as the US has done repeatedly in many south American countries.
