Why Russians would plant all those bombings (and other atrocities) against themselves to make Chechens look bad, if Chechens did not cause them problems by commiting numerous terrorist and criminal acts?
If Chechens were peaceful (or rather if they were not taken over by Saudi Wahhabis) they could govern themselves as many other autonomous regions in Russian Federation and Russians would not have this headache.
Also are you suggesting that American and Israeli governments also plant the terrorist acts against themselves to make somone else look bad?
Are you suggesting that if the FSB were responsible for some, or all, of the Moscow bombings, then that would be OK, since the peole they were smearing were already killers?
