I hate to break it to you, but you appear not to understand what Islamic terrorists are doing.
Islamic terror serves a strategic purpose, which is to create a general war between Islam and "infidels." Their technique is to get people like you and publius to lump all of Islam in with the salamikazes, and thus ignite such a war. In the case of some on this thread, it is clear that their strategy is succeeding.
Chechen terrorists are not the same animal as your run-of-the-mill salamikaze. They think they have a legitimate excuse for indiscriminately killing Russians, and it's clear they'd be willing to work with whatever group is willing to help them out.
You can't just ignore the long history of warfare between Russia and Chechnya. This stuff has been going on for a couple of centuries. Large-scale killings and deportations of Chechens by Russia have obviously not prevented the rise of Chechen terrorists; and a long history of Chechen guerilla warfare has obviously not gained their independence from Russia. For the Chechens, the Russians are about as close to an "ancestral enemy" as you're likely to find.
