How can a bunch of Europeans and Newyorkeres claim self defense while attacking Palestinians in Palestine? Actually they do not. The Israeli government states more or less bluntly, depending on the audience, that it is its sacred duty and right to ethnic clean Palestine of Palestinians. It is apologetic outsiders that cry self defense.
The Times of Israel published and then removed from its site an essay by Yochanan Gordon that openly called for genocide against the Palestinians of Gaza. A cached version is still on the internet as of this writing.
Gordon’s logic, if one wants to dignify it with that term, is that Hamas calls for the destruction of Israel, and therefore the only way to deal with them is to obliterate them entirely. He used the words “obliterate entirely.”
Nor is he alone. Israel nationalists have been arguing for war crimes at an alarming rate.
Hamas is a party-militia of the religious right. It does say it wants to see the Israeli government overthrown. Its leaders don’t, however, speak of committing genocide against Israelis. They say they want to recover their country, which was stolen from them by the Israelis in 1948. Colonial regimes always produce resistance movements.
The fact is that Hamas was supported by Israeli intelligence in the 1980s as a foil to the PLO, so Shin Bet and Mossad don’t seem to have been worried by the party charter.
