Suicide bombers normally operate in a scenario in which their families and other loved ones are living in hellish situations. Their families have a lot to lose in America.
It was only a matter of time before the press picked up on this in the US. To think that there aren't training cells throughout the west is naive.
Weren't some of the 9/11 guys from affluent Saudi families? They don't have to be poor to be idealistic crazies.
Yeah, a lot of suicide bombers are relatively well off and educated. I think it's due to Islam preaching the value of education, which is one of it's more appealing attributes. However, you can still radicalize educated people - especially well off educated people who have guilt for their relative prosperity. Luckily however education itself tends to inure people to that philosophy too much, otherwise we'd have a much larger problem than we actually do with home grown terrorists.
