Change of heart about Islam

After seeing today's story from London, and actually doing a little quiet contemplation on the entire affair, I have changed my mind and offer a different reason for all this crap in the world involving "extreme" Muslim jihadists.
I am now convinced that death and terror are NOT the real aim behind these attacks many others. The extremist leaders WANT to create an atmosphere of persecution around the globe. They want Islam to be the religion that people love to hate - because an increasing number of believers are so willing to kill people to advance their "cause." By striking at the heart of the Western/Chrisitan world, the aim could be to have those people strike back, causing an even larger rift between the two cultures. In many ways, that is how the U.S./British involvement in Iraq is viewed - not as liberation (the fundamentalists don't want to be liberated; they want subjugation) but as occupancy - Muslims living under the Judeo-Chrisitan thumb ... as it has been often throughout history in their eyes.
The more anger built up in the U.S. and Britain, the easier it is to create the role of oppressed people and makes it easier to recruit young people, stupidly willing to sacrifice their lives and others for a cause they know little about. It just sounds exciting and, besides, isn't 18 old enough to die?
Notice the elders NEVER do the sacrificing (not unlike other armies from other civilizations). Older Muslims in the West, who have grown accustomed to the face of prosperity, don't like upsetting the apple cart. But if THEY begin to think of themsevles as part of an oppressed religion, they will become more sympathetic to the bombers' cause. They won't actively join, but they won't help stop it.
Americans assume that only stupid people would do these things. No, gullible youth blow themselves up for men that are quite clever and intelligent in their planning, execution, intent, recruitment and drive. Our real question is how can we prevent this when flashing our "shining light of democracy" has proven to be totally worthless.
I'm still not sure that "Kill 'em all and let Allah sort them out" is a viable alternative. But whatever has taken place up til now, including Iraq, ain't working.
