When I look at a map of Russia just on a precursory basis, they could let Chechny and Dagestan secede and it doesn’t seem like it would be a big deal.

Tiny countries, er territory, Chechnya is.
2 things,
Doesn’t want a precedent set,
And check what natural resources these two seemingly worthless places present.
