I don’t think one can export democracy or rights anywhere in the world, both come from the inhabitants of a country, if they are ready, if a lot of things go in the same direction at the end democracy and human rights could (not have to) spring up.
Hence I don’t believe we can force Ukraine to be more democratic or at least more human with its prisoners, notably the most famous prisoner former Prime Minister Yulia Tymoshenko. But we can do a lot to freed her!
If the main European countries boycott Euro 2012 we can send a message everywhere in the world, we in Europe do not tolerate those abuses!
I really hope they will go forward, we will not change the country, but we can save a life, and I don’t think this is a bad achievement.
Anyway if someone wanted to be a little bit polemical could wonder why such an important event was assigned to a country that was not so different years ago…
