Thanks for the link very informative. After viewing it, I wonder what would you propose, in how to solve the crisis ? 

I can see why the protesters are upset because the President unilaterally made decisions against the peoples Constitution? Trying to go back to a dictatorship.   

NYT report from Kiev in today's print basically describes same: initial protestors of right wing national groups joined by left/liberals and unhappy unemployed youth, etc., as the government reacted: Converts Join With Militants in Kiev Clash

There's a clear problem going forward in that the representatives of the "opposition" involved in any truces or talks are still those right wingers alone. There is no representation of the others. This makes for a result like Egypt--strange bedfellows do not  make for a lasting marriage.

BTW the article has parts that describe precisely why I am no fan of "street fighting" and also what I see in the imagery from the conflict:

“What have humanism and pacifism ever brought to any nation?” he asked, clutching a battered metal shield and a metal rod, his soot-blackened face covered by a brown balaclava. “Revolutions are violent.”

I can't fathom how someone who says they are anti-war can romanticize violent street protests. At their heart, the latter are exactly the same thing as war. Anyone who does it or lionizes it is not truly anti-war. It's just that plain and simple to me. These people are the ones who are truly "anti-war":

Many Ukrainians, who doggedly oppose the government, look with horror at the use of firebombs, rocks and, on occasion, guns to oust the president, who was democratically elected in 2010 and whose future is scheduled to be decided at the ballot box in 2015.

Revulsion is particularly strong in the east of the country, where Mr. Yanukovych first made his career in politics, where most people speak Russian rather than Ukrainian, and where Ukrainian nationalist heroes like Stepan Bandera are viewed as fascist traitors.

“We have a genetic memory of fascism here,” said Anatoly Skripnik, a businessman in the eastern city of Dnepropetrovsk.

I see a very strong equivalence here with violent anti-Vietnam war protests which turned off enough people that could have been with the movement. There did not have to be a "silent majority" supporting continuation of the war. The violent protests helped make them a majority.

The gnarly thing is: Egypt revolution Part I did this part right. And it still didn't work out. But again, violence was part of that problem, turning people (hence the "terrorist" label.) Threatening people's security is threatening civilization, always comes back atcha. Only if police cross a line where they are causing more deterioration of civilization than strengthening it will a majority turn on them. Street fighting isn't just as ugly as war, it's usually even more stupid than most wars.

That is an excellent primer.

I think this part deserves repeating:

What does it mean when the wolf cries wolf? Most obviously, propagandists in Moscow and Kiev take us for fools—which by many indications is quite justified.

More subtly, what this campaign does is attempt to reduce the social tensions in a complex country to a battle of symbols about the past. /.../ If people in the West become caught up in the question of whether they are largely Nazis or not, then they may miss the central issues in the present crisis.

Ukrainians are in a struggle against both the concentration of wealth and the concentration of armed force in the hands of Viktor Yanukovych and his close allies. The protesters might be seen as setting an example of courage for Americans of both the left and the right. Ukrainians make real sacrifices for the hope of joining the European Union. Might there be something to be learned from that among Euroskeptics in London or elsewhere? This is a dialogue that is not taking place.

The history of the Holocaust is part of our own public discourse, our agora, or maidan. The current Russian attempt to manipulate the memory of the Holocaust is so blatant and cynical that those who are so foolish to fall for it will one day have to ask themselves just how, and in the service of what, they have been taken in. If fascists take over the mantle of antifascism, the memory of the Holocaust will itself be altered. It will be more difficult in the future to refer to the Holocaust in the service of any good cause, be it the particular one of Jewish history or the general one of human rights.

What I think it means when the wolf cries wolf is that the wolf has gotten much, much better at PR.

importantly, the military is supportive:

Military and police leaders said they would not get involved in any internal conflict. The interior ministry responsible for the police said it served "exclusively the Ukrainian people and fully shares their strong desire for speedy change".

"The organs of the Interior Ministry have crossed to the side of the protesters, the side of the people," new Interior Minister Arsen Avakov told Ukraine's Channel 5 TV.
