Take off the blinders. Russia is a thousand years old and has a long memory. Six years ago is like yesterday to them.

You are correct in chronological terms. But in real terms Bush’s overtures to bring Ukraine and Georgia into Nato were rejected immediately. So, what you bring up as the reason for this situation, is irrelevant to this situation.
Russia is annexing Ukraine because it wants Ukraine, forcibly back into it’s orbit.
