I don't want to make too sharp of a personal point on it but ....... do you know nothing at all about the situation? I don't think you do.
FIRST: Russia is not afraid. Russia is probably the least afraid nation on the globe. Russia wants to avoid war because their historical experience tells them that war is good for no one, except the war-mongering profiteers.
SECOND: Russia did apply for NATO membership. The United Snakes refused because the Yankees want war for the reasons I mentioned in the FIRST part of this reply.
