Questions abound after Iraeli-Syrian tensions escalated last week, further complicating an already profoundly convoluted conflict in the region. After Israel shot down a Syrian surface-to-air missile fired at Israeli jets, one analyst speculates that one of the projectiles may have been an Iranian test, laying the groundwork for deploying nuclear capable weapons in Syria. Security analyst Stephen Breyer noted that the Russian version of the S-200 missiles launched in Syria are capable of carrying nuclear warheads, and the launches last week could have been a test as to whether such a warhead could penetrate Israeli airspace. After they were successfully shot down, it seems the answer for the time being is no.
