Hasn't Trump spent his entire life compromising with people that he disagreed with? Also, he generally hasn't been compromising with people during his recent run, he's been trying to secure the nomination....which he did. In politics people generally try to demonize their opponents, and Trump has been demonized more than any of the others.
His entire Middle East policy is a complete 180 approach from what we've been doing. So instead of trying to implement govts. or systems over there that share our beliefs, he would rather focus on working with people who share our goals of minimizing terrorism. That seems like a good example of compromising with people you don't necessarily agree with but realize can benefit you.
It's kind of weird you would bring that up since that's what he's spent his entire life doing.
