I see a sort of parallel between the attitude towards Israel, and that towards the Trades Unions
Both Jews and workers were so put upon, and abused throughout history, so many people make allowances for their retaliatory excesses, putting it down to a righting of old wrongs.
Hoever there comes a time when revengs has to stop, and a truce is declared.
Not forgetting that BOTH sides must agree to said truce.
However I fear that intransigence will always rule in both cases.
