Hugs of Sir Manys

Again, there are decisions influenced by beliefs. If the terrorists were atheist, they wouldnt even think about doing such a thing. If Stalin was a baptist or something, he would had done the same thing.

Why are You so sure they would not?

You think everyone who leads those terrorists really believes in those ideals? You think all of them are to fight for islam and none of them are random savages looking for bloodshed? Don't make assumptions that You cannot prove. Many of terrorists are just savages looking for violence who join such movements to fullfil their sick desire to kill people. And they don't care even slightest about who they fight for.

"Many of terrorists are just savages looking for violence" and thats an assumption that you cannot prove either. These people are raised to obey the word of their god (of course interpreted by their religious leaders, be them global or local) and will do anything asked of them. Add to that the justifyed hate theay have for the United States and you have men (or wimen) who will throw their life on a sucide bombing.
