> This capability has been demonstrated multiple times, specially when it was politically convenient, like for example the intercepted Hamas calls that showed that some of the rockets fall inside Gaza by mistake.

Can it be something generated? One can display something that is politically convenient and not true at once.

Of course they knew.

Even if you don't believe in the capabilities of Israeli intelligence, it's well documented that Israel supported Hamas as a hard-line alternative to the PLO to avoid a two-state solution. The Israeli right has for decades intensified the conflict to justify total war against Palestinians. Allowing a domestic attack to gin up support for aggression is in line with their behaviour for the past 3 decades.

I'm old enough to remember when Arafat was well-respected in the west and a two-state solution was the mainstream view amongst Americans. Once Netanyahu came to power in 1996 (30 years ago!) he worked to delegitimize the PLO and pursue an aggressive genocide against the Palestinians.

"Walls of Jericho" plan was known to Israel since 2017. Everything was known but as usually with IDF, too much arrogance and this was mostly ignored. Not to mention the 4am meeting the top brass decided not to raise alarms for fear of miscalculation. Maddening arrogance and many heads should have rolled but still some are in their seats.
