Sorry to hear your fam is this insane, but keep the cookoo takes coming!

Intrigued by your newer posts, I had to see what your parents said earlier. - Wow, this definitely sound like a hard conspiracy theory! Difficult to believe.

But I want to mention, that if you look up different news outlets (even from Israel itself), that is has been established for months now: The Israeli intelligence/military and a bit later Netanyahu had some knowledge about the upcoming attack.

This is still being investigated. And sure, many details are hard to trust and the actions very doubthful. - I am unsure, if this will ever be cleared to the full extend. Unfortunately.
