What is the direct existential crisis facing Russia? Rather, it seems like Putin faces personal embarrassment of his and his nation's perception. From what I've read, the 1999 OSCE agreements say that there is an "inherent right of each state to be free to choose or change its security arrangements and alliances" and Russia signed those.
