"Defeat for Israel--either on the battlefield or via coerced compromises to achieve flawed cease-fires--is a defeat for U.S. interests; it will inspire radicals of every stripe, release Iran and Syria to spread more mayhem inside Iraq, and make more likely our own eventual confrontation with this emboldened alliance of extremists. Victory--in the form of Hezbollah's disarmament, the expulsion of the Iranian military presence from Lebanon, the eviction of Meshal and friends from Damascus, and the demise of the Hamas government in Gaza--is, by the same token, also a victory for U.S. (and Western) interests.
