Republican caution on Syria

Like Dan Drezner, I expected the Paris attacks to increase public pressure for deeper U.S. military involvement in the fight against ISIL. But now Drezner sees a less hawkish trend among GOP presidential candidates -- offset by loud words regarding Syrian refugees and immigration. Most notably, Sen. Ted Cruz sounds a lot like Sen. Rand Paul in this interview.  Since the polls have been inconsistent on ground troops, I guess the pols are holding back. Good.
