But for Americans, the problem of boredom looms larger. Boredom combined with amorality can lead to murder.
How many teenagers like Dzhokhar become gang members out of sheer nihilism? How many commit crimes because they lose touch with a sense of morality? How many losers are just waiting for their Tamerlan -- somebody to infuse them with a sense of purpose, no matter how evil the purpose?
Human beings want something in which to believe. They will fill that void however they must. But in a civilization where Western values have been derided for generations as xenophobic and intolerant, it becomes impossible to fill that void. When navel-gazing faces down passion -- even evil and misguided passion -- passion wins. Pride -- even pride in evil -- defeats multicultural angst.
No matter how difficult it is to accept, Dzhokhar Tsarnaev was not created by xenophobia or hate. He was created by a culture unwilling to defend itself, and he was seduced by an aggressively evil philosophy. Unless America finds the strength to defend her values, there may be many more Dzhokhars in our future.
