Israel is deploying all of its missile defenses as a precaution against possible Syrian retaliatory attacks should Western powers carry out threatened strikes on Syria, Army Radio said on Wednesday.It did not say how many interceptor batteries were mobilized by Israel's air defence corps. The missile defenses include the short-range Iron Dome, the mid-range Patriot and the long-range Arrow II.Facing potentially imminent attack by the United States and other Western powers over its alleged use of chemical weapons, Damascus has hinted it could shoot back at the Jewish state, its old foe. Israel is also braced for rocket salvos from Hezbollah, Syria's Lebanese militia ally.Asked about the Army Radio report, an Israeli military spokesman said: "In light of the recent occurrences in the region, the IDF (Israel Defense Forces) is taking the necessary defense measures to safeguard the State of Israel." He declined to elaborate on the military deployments.Prime Minister Binyamin Netanyahu said on Tuesday that Israel sought to stay out of the Syrian crisis but would respond forcefully to any attempt to attack it.He struck a more calming tone on Wednesday, as Israelis stood in long lines at gas mask distribution centers in shopping malls. Israel has provided its citizens with equipment to cope with possible chemical or biological attacks since the 1991 Gulf War, when US-led troops drove Iraq out of Kuwait."Following a security assessment held today, there is no reason for a change to normal routines," Netanyahu said in a statement after he met with his security cabinet. "We are, in parallel, preparing for any scenario." The security cabinet approved a small-scale mobilization of military reservists, according to an Israeli official briefed on the meeting.
