The link above leads to an article which states that Poland was the main European country to host CIA prisons. The EU has already threatened sanctions against member states who hosted CIA detention facillities, and Poland will probably get the sanctions thrown against it.
This is very, very, good. Poland has been impudent in its obnoxious pro-U.S., pro-free market, traditionalist conservative, stances, all the while while still not coming to terms with anti-Semitism and intolerance in its society.
Poland has probably been the most annoying of the post-Communist states as they tend to be so far right that they're clearly outside of the European norm, yet they want to have all the benefits of EU membership.
You can't have it both ways, and Poland's sanctioning by the EU would be a good way to tell it that if it wants to be part of Europe it better cohere to European norms of legality and justice and not do whatever the fuck it wants, while complaining about the oppression suffered under Communism.
The swifter that Poland experiences real sacrifice due to sanctions from the EU the better.
