Whenever something bad happens, there's always someone saying it's a false flag. While they might be right sometimes, they aren't right 100% of the time. Sometimes, bad people do bad things, and the people responsible for preventing bad things are careless.

For Oct 7, I find "batshit insane violent Muslims" to be a much more believable explanation than "Israel's leadership knew it was coming and let it happen."

There are lots of reasons why Israel's leaders wouldn't intentionally let Oct 7 happen. It decimated their economy, as reservists were called up from their normal jobs, and areas of the country had to be evacuated due to the war. Israel is totally getting clobbered in public opinion, even though their counterattack is justified. Israel also is a relatively small country. Most people know someone who was killed on Oct 7, or know someone who knows someone who was killed.

Israel might not even be allowed by the USA to turn a chunk of Gaza into settlements, which is the only thing they really could gain from the war.
