Well, look at it like this.
No one stopped Bush from invading Iraq, what sort of advice could he provide here?
The way I see it, with any 'fight' that involves Russia, I get worried. The Doomsday Clock is already at 5 minutes to midnight... who knows where it'll be next year... OOOOOH.
Seriously though, this clash between the two countries do worry me. If anything, I do hope that countries (not the UN of course, we don't need a bunch of do-nothing slack jaws involved) get together and create some sort of interim period for peace to alleviate the fighting.
