Since when does Israel need US permission to strike at its enemies, Iran included? No, this is just Israel's excuse for its military impotence to deal with Iran, it has neither strength no guts to attack Iran and is hiding behind the so-called lack of US permission to attack Iran. This statement is tantamount to saying, "Gee! We Israel desperately want to attack Iran but the US just won't allow us for fear that an Iranian retaliation would be just too much for us!" Did Israel need US permission to attack Osirak, Gaza and Hezbollah?
