There has always been a meddlesome quality to the USA that the rest of the so called developed world turned a blind eye to. Along the lines of 'their bastards, but at least they're our bastards'. Of course that does not make it good, but the balance calculation worked out in favor of toeing the line and being careful not to get pulled out of joint too much. 9/11 changed all that and effectively Bin Laden forced the USA to lower its mask for long enough that the world could no longer ignore the bad sides of Uncle Sam. Even that would have not been enough to seal it, but Trump has managed to accomplish this in record time.
