He is somewhat correct Russia basically installed a puppet government and through pretty brutal use of both the carrot and the stick managed to convince the populous that they were in the wrong.
And they proclaimed the Islamic Emirate of the Caucasus that was very similar to ISIS.
Also they didn't stop aggression after Russia lost the first Chechen war and they got their independence. They instead started attacking other non-Chechen territories in Russia that were peaceful until then.
The Russians were right to bomb the hell out of them. And we should do the same if these people don't stop attacking us.
