Hi Limpy...my son wont fight in Ukraine, he is British, his wife is Ukrainian. her family are over there.
The Russians are already in eastern Ukraine...drifted well outside Crimea even though Russia says its untrue (Skype is a marvellous thing - get the facts from real people).
Crimea is part of Ukraine & should stay that way.
If say for example, some tyrant tried to invade Scotland or Wales.....its exactly the same thing. I am a Scot living in England & I would be livid!!! as we are all the UK, so nobody has the right to invade.
CKLD..Yup is using the Russian speaking thing as an excuse, my DIL & all of her family friends etc are all Russian speaking but are Ukrainian...she says nobody is threatening them EXCEPT the Russian invaders.
Long term if he isn't stopped the outlook is scary for the rest of Europe.
