Etc.

Refugees
Angela Merkel and the rest of the EU entered into a devil's bargain to deal with the flow of mostly Muslim refugees, the devil in question being Recip Tayip Erdogan.  I suppose they preferred to deal with a devil outside the EU rather than the nativist devils who put increasingly fascist governments in charge in Poland and Hungary, and are threatening the rest of Europe as well.

Brexit
See above.  The nativists of UKIP are eating away at Britain's Conservative Party, and the controversy over EU membership is threatening to split the Conservatives in much the same way that Tr*mpism is threatening to split the Republicans on this side of the pond.

"Our" Muslims
Obama is pissing off the Saudis.  Good.  It's about time.  Somebody has to do something to end the human rights abuses in Yemen, and cut into support for world Islamism.  While he's at it, maybe something can be done about the buildup of Pakistan's nuclear arsenal, which now seems to include tactical nuclear weapons, and is vulnerable to Taliban attack.

Merrick Garland
Hopefully, the nomination is more a political ploy than a serious indication of the kind of candidate most Democrats want to see on the court.  We've had more than enough "moderation" from Obama himself, and we don't need a Justice who reflects Obama's illiberal views on the primacy of government over individual liberties.
