FILE - In this Thursday, Aug. 29, 2013 file photo, Israeli workers are seen at the Shalon gas mask factory in Kiryat Gat, Israel. The U.S.-Russian plan to dismantle Syria's chemical weapons is drawing some unwanted attention on Israel's own alleged chemical stockpile and could raise pressure on the Jewish state to come clean about its capabilities. Israel signed the international treaty banning the production or use of chemical weapons two decades ago, but it is among a handful of nations that have never ratified the deal. Israeli officials remain mum on whether the country even possesses a chemical arsenal and say any talk of putting pressure on Israel is meant to divert attention from Syria.
