From outside the US, nothing about him has really been predictable, except that he consistently lies about everything.

The only predictable thing about this American presidency is the total chaos that has been inflicted on the world by millions of intellectually degenerate Americans. This is what the world sees. Almost nobody is making excuses for him, everybody is trying to move on without the US.

So yeah, in that sense another war is simultaneously an unpredictable outcome and an unsurprising outcome.
