It is indeed truly appalling as is the hostage taking. And now Israel is going about creating the next generation of people who feel enough hate to commit that kind of atrocity, as a human being and especially as Jew it breaks my heart. They are destroying any hope for the Palestinians and for Israelis. Which is exactly what Hamas wanted and knew they would get from Netanyahu.
Israel should have gone in with a surgical strike on Hamas, not this wholesale destruction and with an outright stated strategy to beseige innocent people, which immediately and understandably set everyone against Israel (and by extension against Jews everywhere) because Hamas and their paymasters only care about the Palestinian people as a tool to use against Israel, they don't care how many die, in fact it suits them.
I am glad, at least, that in presenting this footage the IDF spokespeople were clear that this violence was not representative of Islam and this is an act of terrorism, not a 'religious war'.
