It's not “embarrassing for Poland” at all. It's the common sense approach and oy veys of Israeli far rights and others will be ignored.
There wasn't a single Polish Jewhater or Nazi collaborator. Not a one. Should President Komorowski be jailed for apologizing for the murders at Jedwabne. Or in Stalinesque fashion didn't that happen. Wasocz? Fiction? And there were other incidents, though as I mentioned, fewer in occupied Poland than any other occupied nations I can think of. Guess I can't say that any more, the correct number being zero. Too bad.
BTW, as I noted earlier the issue of "Polish Death Camps" didn't arise from Israel. The most prominent individuals I can think of using that term of late are American Christian liberals.
