You are wrong
Israel does not act like that.
I get really frustrated and angry at stupid comments like this. Too many idiots around. Sometimes it is due to anti-semitism. Othertimes ignorance and stupidity, which I give you the benefit of the doubt as being the reason in your case.
In actuality, Israel goes out of its way to not harm innocents. They go house to house to ferret out the terrorists when they could simply bomb. They do that to not harm those living there not participating in the terrorist activities. It costs the Israelis lives. Soldiers die doing this.
They don't need to. But they do because of their commitment to civiliziation and respect for human life.
