If every descendant of somebody killed in the Holocaust behaved in the same way as Netanyahu the world really would be in bother. Fortunately, it is only Netanyahu and his small, but influential cabel of right-wing extremists (aided and abetted by us and the USA arming the Israeli state) that are committing the atrocities in Gaza. So let's not come up with "excuses" for him.Revenge is a powerful motivator. And how much of Israel's over-reaction is due to the wounds lying deep in the psyche from the Holocaust and centuries of persecution? Netanyahu's own father was born in Poland in 1910 and was a hawkish Zionist who believed in the expulsion of the Arabs from the new Jewish homeland. He lived to be 102. It is not surprising Bibi is as tenacious and zealous as he is.
I would say the Israeli actions will have guaranteed instability in that region for another 40 years minimum, as well as losing Western goodwill for another 20 years minimum.
In any event, wouldn't it be odd for somebody whose family suffered in the Holocaust, to commit genocide himself? The nazis wanted to remove the Jewish peoples from the earth and decided the best way was to kill and starve them. The State of Israel wants to remove the Palestinian people from Gaza and has decided that the best way is to kill and starve them. Different scale, but exactly the same aim.
