When Obama meets over the next month with leaders from Mideast and other regional nations, he will have a timely opportunity to try to rally the Syrian opposition's main backers around a unified strategy to oust Syrian President Bashar Assad. Jordan, Turkey, Qatar and the United Arab Emirates _ whose Sunni Muslim leaders will meet separately with Obama starting April 16_ are all believed to be arming or training rebel forces seeking to overthrow Assad's regime.
