Who is going to stop him?
Obummer is a pacifist, has no interest in foreign affairs (a major foreign policy update has been sitting in his in-tray for 3 years waiting to be signed off!) and he is dangerously clueless when it comes to
everything international diplomacy. He has started all of his speeches on Ukraine, by telling the enemy what he isn't going to do. This is the equivalent of telling your opponent in poker what your cards are. Idiots like this appease until all other options are untenable so it leads to war, when a much earlier robust response would have avoided it. I'm now convinced that him and Putin will start WWIII between them, probably over the Baltic's. MH-17 shows that when you start a war, you are only partially in control of events which is why they so often escalate out of control. The assassination of two people led to the death of millions in WWI.
In each of his speeches on Ukraine his first sentence has ruled out supplying any lethal military aid to Ukraine. Anybody with a smattering of strategic brain cells knows that you keep the enemy guessing and make him expend time and effort on trying to work out your intentions. A much more robust response over MH 17 would have been, unless Russia backs off supplying heavy equipment to the Russian terrorists, which is killing our innocent civilians, we will not supply troops, but we will supply the Ukrainian Government with whatever military aid they request to match and defeat the terrorists. By this I mean anything short of Nuclear weapons: Drones, cruise missiles, F15's, F16's, Apache helicopters, Abrams tanks they will all be on the table. Putin would then have known he was in a no win situation where the airline tragedy actually gave him a credible bug out scenario, but Putin's buoyed by the west's pathetic response, he has been left with a free hand to carry on destroying Ukraine, while the west does nothing. Putin has now closed his bug-out with domestic reputation intact window of opportunity.

A Russian military strategist in Latvia has already worked out that they only need to put about 500 little green men into Latvia and he will be on his way to having his bridge to Kalingrad and will have destroyed NATO as a credible European defence force in the process. The EU and the US would call it an internal problem, with NATO currently having no forces to deal with such a situation or currently have the training courses to train the Baltic counties local security police and special forces to deal with it either.

Merkel in all of her political career as chancellor has always backed away from policy commitments in the light of opposition, to the point of abandoning the policy. I'm sure with a nudge, nudge, wink, wink from Putin: You give me a free hand in Ukraine and I will see you all right on your gas at the right price and your sale of VW's, BMW's and Merc. will always be welcome in Moscow, she would agree to this unofficial back door deal.
Cameron will do whatever his focus groups tell him will make him and his party the most polular for re-election next May.The man has no personal principals that I have ever seen. His guide to policies and spin are what today's focus group' results tell him will make him most popular.
France will not want to do anything which interferes with their nice little earner of rearming Russia with western standard weapons for use against us.

All other EU countries either have too many economic problems due to the Euro, insufficient political clout or both.
EU foreign commission lady ashton (no capitals I'm afraid she isn't worth the effort of pressing the shift key) has been an frightful embarrassment even by EU standards and as a life long pacifist and ex-cnd secretary, no more needs to be said.
