the leader of israel cant go to the holocaust museum because hes a convicted war criminal and would go immediately to jail!
the museum was made for crimes against humanity but the leader who would go to commemorate it was found guilty of crimes against humanity!
they made a museum for people who were victims of humanity crimes but now their nation has been found guilty of the same!
and so if he goes to commemorate the one crime against humanity he will be jailed for the other!
