I mean the property back then belonged to Poles (Poles of jewish faith), no?
What has that to do with the US???
Property of US citizens with Polish roots no matter of what faith is referred to as American property. As per agreement between PRL and USA dated 16th of July 1960 Poland agreed to pay the compensation for the loss of the private property to those US citizens who made such claim prior to this date in the form of the said sum. The very same agreement stipulates that any future claims after this date filed by the former citizens of Poland who become US citizens or her legal residents will be the soul responsibility of the nation that granted the citizenship to such person, furthermore by signing this bilateral agreement both side consider it a closed matter with all debts settled. Mind you, Poland made similar agreements with various nations at the time not just US.
What does he mean with that?
LOL Diplomatic way of saying (feck off) we do not really care how US classifies its citizens, in the eyes of the law there is no difference based on ones religious preference, all are her citizens and Poles with equal rights, if U.S makes that distinction it’s their right but Poland does Not so there’s no need to put an emphasis on one special group.
