Karl Cordell, Stefan Wolff, Germany's Foreign Policy Towards Poland and the Czech Republic: Ostpolitik Revisited, 2005, p. 139: "In addition [...] it has been relatively easy for Polish historians and others to attempt to debunk communist historiography and present a more balanced analysis of the past - and not only with respect to Germany. It has been controversial, and often painful, but nevertheless it has been done. For example, Poland's acquisition in 1945 of eastern German territories is increasingly presented as the price Germany paid for launching a total war, and then having lost it totally. The 'recovered territories' thesis previously applied in almost equal measures by the communists and Catholic Church has been discarded. Some circles freely admit that on the whole, 'the recovered territories' in fact had a wholly German character. The extent to which this fact transmitted to groups other than the socially and politically engaged is a matter of debate. [1]" ISBN0-415-36974-6, ISBN978-0-415-36974-9
