I will repeat myself:
No, he isn't, he doesn't want to. His official policy is "America first, fuck the rest!". Where is he leading the (free) world to? Is he pressuring for a new accord to replace Paris were everyone uses more coal? As a Mexican, what is he asking us to do other than pay him for the stupid wall?
The only international movements he machinated and supported so far is the Qatar blockade and China "tried" something with North Korea, but those doesn't count, as all the main participants are authoritarian regimes. He seems far more comfortable dealing with authoritarians than the actual free world, that often openly challenge him, and even mock him.
Heck, even his own admin contradicts him on the Qatar issue.
