[In Syria, America Loses if Either Side Wins](http://nyti.ms/15yXFwd):By tying down Mr. Assad’s army and its Iranian and Hezbollah allies in a war against Al Qaeda-aligned extremist fighters, four of Washington’s enemies will be engaged in war among themselves and prevented from attacking Americans or America’s allies.Non-Sunni Syrians can expect only social exclusion or even outright massacre if the rebels win, while the nonfundamentalist Sunni majority would face renewed political oppression if Mr. Assad wins. And if the rebels win, moderate Sunnis would be politically marginalized under fundamentalist rulers, who would also impose draconian prohibitions.Maintaining a stalemate should be America’s objective. And the only possible method for achieving this is to arm the rebels when it seems that Mr. Assad’s forces are ascendant and to stop supplying the rebels if they actually seem to be winning.This strategy actually approximates the Obama administration’s policy so far.
