U.S. Spies Root for an ISIS-Russia War

Now, six U.S. intelligence and military officials told The Daily Beast that they hoped an ISIS attack on Russian civilians would force Putin to finally take the gloves off and attack the group, which the U.S. has been trying to dislodge from Iraq and Syria for more than a year, without success.

“Now maybe they will start attacking [ISIS],” one senior defense official smugly wondered last week. “And stop helping them,” referring to ISIS gains in Aleppo that came, in part, because the group took advantage of Russian strikes on other rebels and militant outfits.
