LONDON - The Boston bombing was major blowback. That much is certain. The question is, what level of blowback?

It could have been a covert op gone real bad. It could have been blowback from former ''freedom fighters'' - in this case ethnic Chechens - reconverted into terra-rists. It could have been straight blowback for United States foreign policy targeting Muslims, whether dispatching them to Guantanamo, Abu Ghraib or Bagram, extraordinarily renditioning them, or target assassinating them.
