I am sure Israel can hold its own ground. And any preemptive strike will only serve to provoke a war sooner or later. I think Israel is strong enough to deal with any threat to its borders. Having said that it will be a morale sin on every single human on this planet to attack and corner Jews, they are people just like us and i always hate it when others(religions) speak ill of Jews infact, the Jerusalem is a holy place for Christians and Muslims but its the birth place of Jews. Pity that religions decided to stage their games on a single place, where innocent Jews were caught in the middle.
