So, it seems the Israeli government knew something was going to happen and then let it happen so that they could steal more land in response.
WTF is wrong with them.
It's what Jesus wants them to do
Err.. Jews aren’t really so big on Jesus friend. I get your point though.
While I also hold this suspicion, there is fairly little evidence of this.
However, I'd say the biggest evidence is that it was literally the 50th anniversary, down to the same holy day, of the last time Palestine forces attacked Israel. The fact that Israel didn't at least have some sort of elevated defense last Saturday is absolutely unforgivable. This is not quite a smoking gun, but definitely at least gun smoke.
There are two possibilities I see. Either Israel knew it was going to happen, and let it, or they didnt know. Both are unfathomably irresponsible, and unforgivable.
Israelis should be tearing their own government apart for their ineptitude and/or treason, and likewise, Palestinians should be tearing Hamas apart for being so stupid and impotent.
I think calling their lack of preparation for something that hasn't happened in 50 years suspicious is a stretch, regardless of whether or not there was an anniversary.
Egypt warned them days before, the USA has confirmed the warning by Egypt. Hamas has released training videos showing the paratroopers training with flying gliders. Yair Lapid released a video in September warning the government was ignoring intelligence signals.
I see a clear picture emerging.
You often see reports after a successful attack that "so-and-so warned such-and-such about this-and-that days before attack", but they almost certainly get dozens of warnings a day from lots of sources. Some are right, some are wrong. The attacker only has to be lucky once. The defender has to be lucky every time.
That's not to say that Israel won't capitalise on the chance to flatten Gaza, because I browsed /r/combatfootage and have eyes, but I think they'd rather not have hundreds of Israelis held captive and over a thousand dead.
Certainly not the first time something like this has happened.

Evidence Israel knew / was forewarned about the attacks
I’m not gonna allege specific knowledge of this attack, but there is plenty of evidence that Netanyahu and his cabinet saw continued provocations by Hamas as a key to retaining their power.
Whether he did anything to make it happen, an attack like this was very much on his wish list.
