Not a Jew, not an evangelist. Just a Christian. I know what God told the Israelites to do to the Canannites.
"But thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites; as the Lord thy God hath commanded thee:" Deuteronomy 20:17 (KJV)
The Jews were commanded to "utterly destroy them" but it turns out the Jews didn't do that. Why? Perhaps the commandment was more about getting them out of Israel and not killing them all. But the biggest difference is that these were the only people God told the Jews to "destroy". It wasn't an open ended commandment to kill all unbelievers in perpetuity.
You also need to realize that God is the author of life. He can give it and he can take it away. But Allah is not God. Allah is a figment of Mohammad's imagination. Allah is the excuse that Mohammad came up with to justify his blood lust after he got thrown out of Mecca his second time.
