Israel has assured the US that its recent moves in the Golan Heights will be temporary, as Israel is responding to legitimate security concerns in Syria. Neither Israel nor the US want to see Assad's chemical weapons fall into the hands of extremists, and Israel's actions will help ensure stability and security for the entire region.
Israel's presence in the Golan Heights is not just a security imperative but a moral concern. Thousands of Druze live in the area and many have expressed their openness to Israel's presence to defend them from the possibility of sectarian persecution at the hands of the new Islamist government in Damascus.
The US, as always, is backing Israeli expansionism at the expense of the local population. The new government in Damascus has not done anything to elicit Israel's violent and aggressive military actions in the last week. Indeed, though Israeli media might focus on the comments of a small minority of Syrian Druze, the community as a whole is firmly Syrian and clearly does not desire Israeli occupation.
