During World War II he served under General Władysław Anders in the Polish Army and kept up friendly contacts with representatives of other nationalities . After the war he moved to Paris , where he published and edited a leading Polish-émigré literary-political journal , '' Kultura '' ( 1947 – 2000 ) , which promoted a peaceful settlement of Poland 's eastern borders , and accepted the results of the Molotov-Ribbentrop Pact and the Yalta Conference , the ( Giedroyc-Mieroszewski doctrine ) , even though many Poles regarded these as betrayals of Poland . This helped to lay the groundwork for Poland 's successful eastern policy after the fall of communism . His closest collaborator was Juliusz Mieroszewski , who provided the theoretical justification for Polish recognition of the borders with Ukraine , Belarus , and Lithuania ( whose future independence he predicted long before it came about )
