Spam, wonderful spam (bloody vikings!)
So why not just not join Nato and keep the peace? This is like a person walking up to a person and saying I will get my gang to hit you and your family - what you can do? Perhaps the person will do nothing, perhaps the person will choose to protect his family. Perhaps all bets was Putin had no courage?
Putin's a dictator, and therefore a control freak. He can't cope with the knowledge that Ukraine wants nothing to do with his corrupt empire.
Putin is like a school-yard bully who threatens smaller children to join his gang.
