The uncertain threat of missiles from Iraq during an American offensive is less serious to Israel than the almost certain threat of attacks by Hezbullah from across the Lebanese border. The IDF is likely to respond or launch a pre-emptive operation against Hezbullah, and is also likely to move against the largely untouched Hamas infrastructure in Gaza. This is according to Amir Oren, who also records that an Arrow missile interceptor (successor to Patriot) is launched by pressing the F2 key on a PC keyboard.
