The fact is Israel is an apartheid state with Palestinian's occupied in the West Bank and Palestinian's in Gaza held in an open air prison Israel has occasionally invaded and bombed with impunity since it tore down the Israeli settlements and "officially" withdrew from it.
Saying this has nothing to do with anti Semitism or the Holocaust-those old standby accusations toward anyone critical of Israel.
As to Pompeo one uncorroborated report had it as an attempt to help Benjamin Netanyahu remain as prime minister of Israel. He continues as PM because he nor his rival Benny Gantz have been able to form a new government since the election two months ago. Another election may be called for.
That one is too complicated to get into this short space.
