There was a debate on the Ukraine yesterday and you can read my comments and other participants here: http://www.publications.parliament.uk/pa/ld201314/ldhansrd/text/140318-0001.htm#14031876000361
I do think the present situation is dangerous and will not end quickly. The east European countries are worried and so are some of the other countries in the Caucuses.
It is the way that Putin is playing the nationalist card that creates the danger of losing control of ethnic feelings in a number of ex Soviet states.
Do remember that just as many people are currently saying ‘we don’t want a war’ so the same was said in 1913 – there are some worrying parallels.
On an interesting aside, as chairman of the Mary Seacole Memorial Statue Appeal I arranged for the sculptor, Martin Jennings, to go to the Crimea a few months ago to take a cast of the land there for the Seacole memorial – I am very relieved that we got in just in time!
