Obama Expected to Push for Gulf Missile Defense at U.S. Summit

According to U.S. sources, President Barack Obama is expected to make a renewed U.S. push next week to help Gulf allies create a region-wide defense system to guard against Iranian missiles as he seeks to allay their anxieties over any nuclear deal with Tehran. As Obama tries to reassure Gulf Arab countries that Washington is not abandoning them, U.S. officials say the offer could be accompanied by enhanced security commitments, new arms sales and more joint military exercises.
