My statement was that Israel's creation in the 1940s is what caused such resentment against the west and what allows such radical groups to rise.
One does not create a bonfire without a lot of burnable material. The ISIS is a bonfire of hate and the west has given them plenty of fuel. Israel was the start.
As far as ISIS goes, the fundamental fact is that if they are permitted to go any further than they have gone, they will change the Middle East fundamentally. They MUST be destroyed. Every single member of ISIS, and every follower thereof must be killed, along with Boko Haram, and any other group that has similar ideals. Their continued existence on Earth is a threat to the continued existence of the human race. Even assuming we allow that Islam has a moderate wing (which I don't believe, but for the sake of argument), groups such as this MUST be destroyed completely.
This is why I don't take your claim of having a major in history seriously. Completely destroying a group is very hard. Nearly impossible really. Sure you can smash a country and wipe out a race, but an idea, a belief, is much harder to kill.
Jewish history is full of times when being Jewish was forbidden or punished. The Egyptians, according to your own holy book (not really scholars) tried to cull jews but failed. The Romans tried to ban, tax, and exile them. The Nazi's tried to wipe them out. They all failed.
Druids: Romans tried to wipe them out. Didn't work.
Catholics vs Protestants: Nope.
Hell, America has still failed to wipe out all the Indians.
And what happened? The group usually got more power. Especially the Jews and Protestants.
Oh and let's not forget the Crusades tried wiping out or converting Muslims. Didn't work out so well either.
So yeah, let's try to wipe out ISIS. We'll just have them back in a generation, stronger than ever. American still can't get rid of the damn confederates and it's been over 100 years!
I personally think the US should cut off all contact with Israel. No trade, no supplies, no military support, nothing. I can guarantee you, Israel would not survive a decade(I am aware of their defense industry but you can't make a gun without metal and you can't fly a jet without fuel) and within 50 years of no interference from the West(and a massive drop in oil needs), peace in the Middle East would be had.
