I know t is a topic dear to your heart and a lifetime’s work despite the brutal attacks on the country you admire so. I suppose the answer is that antisemitism still lingers in in Poland (as it does thankfully in Sanaa) which although now more prosperous & mostly Judenfrei , a EU/Nato member they are hardly like to want to welcome , say, 5 million of the chosen people however much gilt they bring with them to their new Shetetls. Keep up the brave fight to expose them here & elsewhere
