Our president feels forced to change one of his past pledges – though just slightly, so far. He's sending about 50 soldiers into northern Syria, something he vowed repeatedly not to do. But after a year of American air strikes and the failure of a U.S. program to build an army of Syrian rebels, President Obama last Friday ordered special operations troops to step up the war against the terrorist group known as ISIS (Islamic State In Syria). It's the most significant escalation so far in our campaign against the militant Muslim group that controls large areas in Iraq and Syria.

American ground fighters have struck inside Syria before in swift raids, but these four dozen military men will stay up to two months at the headquarters of U.S.-backed fighters from the region. They’re due to land by late this month, and the Pentagon says more could follow. The deployment follows the first death of an American military service member in the fight against ISIS. Master Sgt. Joshua Wheeler died Oct. 22 in Iraq during an otherwise successful rescue of hostages held by ISIS.
