Why ISIS is like Donald Trump
From Kevin Drum at Mother Jones:
Basically, everyone is willing to give lip service to fighting ISIS, but for most of the actors in the Middle East it's not really a high priority. They'd rather keep their powder dry for the main event. In that respect, ISIS is sort of like Donald Trump. All the other Republicans want to get rid of him, but they don't want to spend a lot of their own energy doing it. They want someone else to do it, so that it will be someone else who's too worn out to win the actual nomination fight.
Even so there's some recent progress in the campaign against ISIS.
