What happened to Gaza on that day?

Decades prior to Oct 7th, the IDF was shooting children through fences and ethnically cleansing villages.

Israel has been doing a similar thing to "1st amendment auditors", the people who harass random people and police in order to get a reaction and sue. They got the reaction, now Israel is attempting to play the victim. You cannot put people in fences, force them through militarized checkpoints, and allow settlers to harass and assault people in their homes with military backing and even begin to pretend to be the victim.
