In the light of the recent tragedy in Boston, we ask ourselves once again why anyone would commit such diabolical and abominable acts. What could possibly have motivated Dzhokar and Tamerlane Tsarnaev to become terrorists?
Some have blamed social isolation, video games, and the conflict between Chechen separatists and the Russian government. The U.S. has never had boots in Chechnya, in fact, during the 90's, many American politicians and lobbyists were sympathetic to the cause of Chechen independence. All of these theories have missed the elephant in the room, which is Islam itself.
The basic tenets of Islam mandate sharia law and the subjugation and terror against infidels, in anticipation of the day when all of the Earth becomes "Dar al-Islam", either through proselytization or force.
