Oh im not saying every single thing the US has done under the guise of protecting democracy was correct. ( i should have elaborated as much in my reply ) Im not saying we have some excellent record of it either.
There are instances where US policy makers were beholden to other interest groups that "clouded" their judgement. No doubt.
I look at Taiwan not from an angle of "what is our track record" but from "what do the people want" and i dont think of it along the lines of "and synergistically to US interests" - although, as you pointed out, does play a role in where we choose to take a stance.
