The Ceasefire is dead, officially: http://www.theguardian.com/world/201...tes-debaltseve

More sanctions have also been issued: http://www.theguardian.com/world/201...s-list-ukraine

We're getting quite close to Putin himself being persona non grata, I don't think that will happen but at this rate he'll be the only official allowed to travel.

I can't see how Obama can resist supplying Ukraine with arms now, even though arms will require American "advisers". This is a nightmare scenario for Obama because he now has two options - be the president who "let the Russians have Ukraine" or be the president who "started the new Vietnam."
