ISRAEL - Israel needs to decide if it is headed toward war in Gaza, Avigdor Lieberman says, and a military blow 'is the only way to lower the level of violence to zero or close to zero'. Defense Minister Avidgor Lieberman said on Tuesday that Israel must decide if it is headed toward another war with Hamas in Gaza. According to Lieberman, the security cabinet should order a military blow against the Islamist group "even at a price of moving to a wide-scale confrontation." "My opinion is very clear. We must land a strong blow against Hamas. That's the only way to lower the level of violence to zero or close to zero."
