Blowing yourself up has absolutely nothing to do with courage. Those men and women are so misguided by their belief system that they cannot think for themselves. Remember, they think they are going to......"Paradise" It's the leaders of these misguided fools who hide behind their politics/religion who are the real cowards. I don't see any of the leaders of the terrorist faction blowing themselves up......they aren't that stupid. Cowards always send someone else to fight for them when they can.
