Hmmm...I smell a a storm (front) brewing.
I'm going to paraphrase the ultra right wing blogger Lawrence Auster on this one. In parts of the Torah it said that the Jews wiped out entire communities. Yet in other parts, those same enemies of the Jews (canaanites and philistines) pop up, which might lead a person to believe that the Jews didn't do as G-d told them to do.
Anyway, Auster says that some of those killings did indeed happen. But the difference, he says is that they were just events that happened. The killings were never codified into Jewish law like you see in the Koran.
So if you're really serious, as opposed to being a snot-nosed troll, you can go and check his blog for yourself --

In the Koran, you have suras that say do not take Christians and Jews for friends, kill the infidels wherever you find them, cut off their ears and noses, etc. Furthermore, there's no equivalent in Judaism to jihad.
