Not sure about that but an irony about the massacres is that Kibbutzim Israelis (and perhaps music festival attendees) are more likely to be lefty type peaceniks than other Israelis. No not saying they all are or anything like that but if Hamas was a normal political group seeking a peaceful solution rather than the Jew murdering terrorist organization they actually are, they have killed (and lost the sympathy of) some of the best Israelis (from a Palestinian human rights POV).
Anyway, any talk of a two state solution which was already mostly dead on both sides is much much deader now after the Hamas pogrom.
Great work, Hamas terrorist scum!
