Find new digs in Somalia?  China and Russia would love that move.  They'd each bid against one another to move the thing to one of their countries.  Maybe create some new UN center along their border.  It would be a disastrous loss of US eminence in the World.

Trump is an idiot.  He opened his mouth about the UN during his campaign (like the wall, and Obamacare, and NAFTA, etc.) and now he has to appease his base by roughing the UN body up.

He gets away with that here in the US.  One thing Trump's Presidency has made clear, and which I personally am proud of America for, is that even in the face of profound disagreement, we all substantially seem to still put law and order and country first - some would argue that we are TOO civilized. 

But the rest of the world doesn't operate that way.  Their "respect" for the office of POTUS is essentially that same as our "respect" for XI, or Putin, or . . . name another world leader.  For ALL, a weaker US has positve benefits. . .
