I don’t know how the jihadist goal is mixed with some kind of Chechnyan natonalism. The answer is important to Russian response.

They have already clobbered Chechnya pretty badly in the last decade.

Putin has to do something for domestic political reasons. I question whether it will be effective, or it will go after skapegoats.

Furthermore, there may be more to come in the near future. After all, we had 4 attacks, we could have more.
