What's going on Ukraine right now isn't quite as exciting - or, probably, as momentous - as the events of August 1991, but it's still a big story.
A Fistful of Euros has been giving it a lot of coverage, as well as links to other sources (including blogs from within Ukraine itself).
As a small-d democrat, I have to root for Yushchenko and his supporters; the current administration is corrupt and may be criminal. However, to have a Western-oriented government take power in Ukraine would certainly anger the Russians, with unpredictable results. (Events in the former Georgian SSR already have them ticked off, and Ukraine is a much bigger prize.) There's already a conspiracy theory out there laying the crisis at the feet of Polish and American politicians, notably Zbigniew Brzezinski, aiming at simultaneously weakening Russia and creating a power base for Poland within the EU, countering the Franco-German axis.
I'm keeping an eye on this one.
