That won't happen any time soon. To join the EU Ukraine has to meet requirements like a stable government and economy. And that won't be the case for the next several years.
And Ukraine will bring Yanukovich to trial for mass murder.
And I don't think the lesson is that if people want democracy they have to engage with far-right. The lesson is: They have to engage.
The first problem:
The state is able infiltrate and subvert all political movements, and beyond; even animal rights activism and Ufology, as they do in the UK.
(I am sure that you already know that attempts to ban or prosecute Germany's NPD have met with failure, because there are so many state agents who have infiltrated the movement, and have even acted in a way that would encourage prosecution, and the state does not want to lose its assets, even if people die, as a result.)
This is the first way in which the state apparatus subverts democracy, and they get much better at doing so with the passing of time.
Nevertheless, in so far as any political movement is excluded from political protest or the democratic process, it is undemocratic.
I make the point because in "liberal" democracies, which Ukraine was not, certain political groupings are maintained at a level that keeps them outside the democratic process. In the UK, these are known as extra-parliamentary movements. This means that they are denied expression.
I shall illustrate:
In the UK in 2003, a conservative estimate of 750,000 people marched in opposition to the Iraq War. Led by establishment left-wing luminaries such as:
Among other high-profile supporters were writer Tariq Ali, ex-minister Mo Mowlam, London's mayor Ken Livingstone, actress Vanessa Redgrave, human rights campaigner Bianca Jagger and former MP Tony Benn.*http://news.bbc.co.uk/1/hi/2765041.stm
There is no reason why you should have heard of these people, but they are all establishment approved reds.
What this march did not do, despite public opinion being right behind them, was march into the Houses of Parliament, which would have been a good piece of direct action.
Instead, they had an emotional outpouring in a public park. They were bogus. The Establishment manages dissent in order to render it ineffective. The far-right are more sincere, more individualistic, less easy to manipulate, and if they were to be given a platform, they would pose a far greater threat to the establishment.
I am 100% sure, that at least... ooh... at least 70% of folks reading this post would agree with excluding the far-right from the political process... or worse, and they have been propagandised into thinking this way.
This is one reason why the political scene is so dead in liberal democracies. Liberal democracies are not so democratic.
My other suspicion is that Ukraine will become a de facto
EU member state after accepting a bail-out from the EU.
