Continue bombing ISIS where potentially efficacious, as heavily and for as long as needed. This week's bombing forced them to give up the dam they'd seized at Mosul, an act that left ISIS looking, for the first time in its history, reduced and stoppable. Go to Congress for authorization of force, showing the world we have gained at least some semblance of unity. Give the Kurds, our actual friends, every kind of help they need, from military to material. Use the threat of ISIS to forge new bonds with allies and possible allies, such as the leaders of nearby countries that are immediately threatened. Go to the U.N., pound the table, ask for the world's help. Let them humiliate themselves by doing nothing if that's what they choose. At least it will be clarifying.

And be prepared, to the degree possible, for a hit or hits on American soil or that of our longstanding allies. ISIS says it's coming. So far they've done pretty much everything they said they'd do.
