Vilhelm Konnander's Weblog has an important post on the political turns of contemporary Poland:

How to deal with the past, has become the central issue in Polish politics with the rise to power of the Kaczyński twins. Their policy of lustracja represents the wrath of the malcontents - a revanchist policy for all those former dissidents, members of Solidarity, or ordinary people, who never got a slice of the pie during the 1990s' privatisation. Their populist target is the "Salon" - communists, apparatchiks, bureaucrats, and collaborateurs, who were able to benefit from the privatisation schemes as only the very top echelons of the communist system were removed from power. However, having not previously dealt with history has made most politicans potential victims of persecution, as more or less fabricated scandals about a communist past have often come in handy when populists or others have wanted to permanently discredit next to any public figure. Being able to taint leading personalities of the Solidarity generation, has become a method for young and aspiring politicians to make careers and gain power by removing their seniors by rumours and allegations.
