re: This is the real reason for all the Ukraine support

Putin only cares about Russia. That makes him predictable. If you are being objective you can reasonably see how Russia would be concerned about a potential NATO member on their doorstep. NATOs only purpose is to be an anti-Russia military coalition. We have a demonstrable tendency to engage in hostile “regime change” with minimal justification. I would say Putin worries about these types of things. The reasonable thing to do would have been to say no countries touching Russia will be invited into NATO and then to have armed Ukraine so they could defend themselves. We didn’t do this and I’m not spoiling for a “forever war” with Russia no matter how much Romney and Cheney want it.
