I believe I saw a story about a Russia state media person proposing using tactical nukes on their own territory. I don't think they actually would, but Russia may... Let the enemy group up in your own territory, and nuke it... other than humanitarian concerns for their own citizens, other countries ability to complain would be dulled if they were nuking their own internationally recognized territory.

Honestly, probably a great tactic to act as a deterrent in future wars (such as with the US).

I've caved by the end of this message... no sane person would, but I wouldn't call Russia's current government sane.
