Ignatius: A proxy war creates Syrian chaos

ISTANBUL - The squabbling factions that make up the Syrian "moderate opposition" should get their act together. But so should the foreign nations - such as the United States, Turkey, Qatar, Saudi Arabia and Jordan - that have been funding the chaotic melange of fighters inside Syria. These foreign machinations helped open the door for the terrorist Islamic State to threaten the region.

From the beginning of the revolt against President Bashar al-Assad in 2011, Syria has been the scene of a proxy war involving regional powers: Turkey, Saudi Arabia and Qatar all wanted to topple Assad, but they competed with each other as regional rivals, too. At various points, all three nations provided Sunni rebel groups with money and weapons that ended up in the hands of extremists.

Outside meddling in Syria worsened when the Shiite-ruled neighbors, Iran and Iraq, dispatched Hezbollah fighters and Iraqi militiamen to rescue Assad's army.
