I agree on the second point. As long as the power backers are still there, and they aren't going anywhere short of a civil war, the USA is an enemy. Even if they elect someone else nothing changes.
I disagree on the first point. Yes, his verbal diarrhea is so continuous and stupid that it's hard to keep listening, but everyone needs to take it seriously. Hopefully, without giving him much attention. By posting images like this and spouting similar sound bites he's questioning the legitimacy of these countries sovereignty. If as a global community we start accepting that, then it's a slippery slope to accepting that these countries aren't "countries" worthy of their sovereignty. Then his map happens.
