Bolded for truth. People are ignorant of the cost of the last war - Chechen war's - on the normal civilian population - Chechen militants were able to pull acts of sabotage and terrorism deep in Russia. Probably going to get downvoted for this, but both Russians and Ukranians have a sizable population that look/act like the other, and the border is not that hard to cross. This means it's really easy for one side/both sides to do nasty covert missions on each other that will probably hit civilians. Stuff like blowing up bridges, air planes, gas lines, supermarkets and other high value targets.
