Arab leaders agreed on Sunday to form a joint military force after a summit dominated by a Saudi-led offensive on Shiite rebels in Yemen and the threat from Islamist extremism.

Arab representatives will meet over the next month to study the creation of the force and present their findings to defence ministers within four months, according to the resolution adopted by the leaders.

“Assuming the great responsibility imposed by the great challenges facing our Arab nation and threatening its capabilities, the Arab leaders had decided to agree on the principle of a joint Arab military force,” Egyptian President Abdel Fattah al-Sisi told the summit in the resort town of Sharm el-Sheikh.

…James Dorsey, a Middle East analyst with the Singapore-based S. Rajaratnam School of International Studies, said that despite support for a joint-Arab force, “it would still take months to create and then operate on an ad-hoc basis.

“I don’t think we will get an integrated command anytime soon, as no Arab leader would cede control of any part of their army anytime soon,” he said.
