What's the French definition of "proportionate response"? Throwing down their weapons, raising their hands, and flying a white flag?
Israel must use ONLY a proportionate amount of force. This means using no more force than that required to DECIMATE and DESTROY WILLPOWER TO FIGHT of Fatah, Hamas, Hezbollah, and if required, Syrian and Iranian military. NO more, and NO LESS.
.......that and crapping their pants ......
A good head butt is all that is required.
