An article I read some time back explored why many terrorists of the Islamic bent seemed to be well-educated, had spent some time in American/European universities, and often had established careers in "the west". The speculation was that some of those who came to "the west" and tried to stay longer term had a hard time adapting. This portion tended to become radicalized. The article further speculated that if they had stayed in their country of origin they would have been happy and not been radicalized. Of all career paths someone in the middle east might choose, the one their societies/families deem most worthy of the extra expense of a western education is engineering. Engineering + Islam might not be the key to radicalization, rather it's Exposure-to-West + Islam that seems to be the stimulus for radicalization. And Engineering students from the middle east have a much higher Exposure-to-West level than, say, art historians or geographers.
