In Central and Eastern Europe the interpretation of the outcome of the Munich Crisis of 1938 , and the Yalta Conference of 1945 , as a betrayal of Central and Eastern Europe by Western powers has been used by Central and Eastern European leaders to put pressure on Western countries to acquiesce to more recent political requests such as membership in NATO
