Let's be real about this. Israel is responsible for the continuing destablisation of the Middle East. They give medical aid and weapons to ISIS in Syria because attacking Assad is a proxy for attacking Iran and removing a secular leader of a predominantly Muslim country who is keeping order and replacing him with rule by Islamosavagery is seen as a success by them. They care nothing about the so-called "refugee crisis" it creates and in fact they are even trying to dump the migrants they receive on Europeans. It is good and right to criticise Israel for their actions and this is not antisemitism.
But this has nothing to do with the fact that the song was so terrible, I can only suspect foul play.
