In pursuit of a more nuanced approach to the history of Polish-Jewish relations that includes Jewish recognition of Polish losses suffered during World War II, the WJC's Research Institute published two monographs which explored the attempts to revive Polish Jewry and the ways in which Poles and Jews have confronted their common history. Moreover, the Israel Council on Foreign Relations, which operates under the auspices of the World Jewish Congress, together with the Polish Institute for International Affairs, held two successive conferences (one in Warsaw in 2009 and the other in Jerusalem in 2010) to discuss bilateral relations and international issues of mutual concern. At the second gathering the 20th anniversary of the re-establishment of relations between the two countries was marked.
