In an effort to increase its negotiating leverage during Syria peace talks in Vienna, the Obama administration has adopted a combined military and diplomatic approach that resembles a strategy employed last year to strong-arm Iran into negotiating with the West over its nuclear program.
In Syria, as in Iran, Washington is trying to pressure defiant parties into accepting the West’s terms by changing facts on the ground.
With Iran, it was economic sanctions, an increased military presence in the Persian Gulf, and a covert intelligence war. With Syria, it is a timeline for the departure of Syrian President Bashar al-Assad, the (perhaps symbolic) deployment of 50 special-operations forces to northeastern Syria to help local elements fight ISIS, and a covert CIA program to arm moderate Syrian rebels with antitank missiles.
