Territorial acquisition is a dangerous game to start playing. The world has moved on from the age of annexation and invasion.

Clinton has compared this to Germany in 1930s. There are some parallels. Being sore about having lost territories in the break-up of the soviet union. Annexing neighbouring territory on the grounds of protecting your ethnic clan. Promising that you are finished when there are many other Russian ethnic groups in other neighbouring territories.

The psychology of Putin is a worry. He has a bit of a narcissistic personality cult about him which is a warning sign for a leader who has the potential to cause a lot of misery through ego driven confrontation.

I hope the world can show a united front when it comes to sanctions to see if we are able to control bad behaviour without military force.
