"Yanukovych has gone, the same way most dictators go"
The point has already been made that he wasn't a dictator in the real meaning of the word, although at times it might have seemed like it to many Ukrainians.
I suspect there will be a time of indecisiveness. not helped by the fact that the Russian Prime Minister has called the forcible ousting of Yanukovych an illegal act. In the longer term, Ukraine will almost certainly end up with another government which will be as corrupt as the one that is being replaced.
I think the real danger lies in Russia's loss of face over this. If Putin does nothing it will be perceived that he is weak and Russia has lost out to the west.
If he sends in the tanks there will be hell to pay, it could cause a civil war between the European leaning west of the country and the Russian supporting East. There will also be much greater tension between Russia and America.
There was ,I thought, a couple of encouraging things :The Ukraine Parliament acted quite well, as did the army. The crowd, by and large, did not loot. There are a couple of big problems: They need a huge bail out - the Russians may withhold their offer, and I doubt that the EU could afford or risk it. Secondly there are many ethnic Russians there and they are unhappy with a shift towards the EU. I suspect Putin will use economic rather than military pressure.
