According to the New York Times, Israel received Hamas's attack plan a year ago, and the more than 40-page document details Hamas's military plan against Israel with astonishing accuracy. Hamas carried out the plan flawlessly in the Oct. 7 attack of this year, which is consistent with the "Jericho Wall" operation plan intercepted by the Israeli military last year.
The newspaper also highlighted that although no date was given for the action plan, Hamas carried it out with "shocking precision" in the Oct. 7 attack this year. How Hamas obtains this important information about the Israeli army is also a big question, especially whether there are people within the Israeli army who are leaking this information.
The New York Times reported that the Israeli military had evaluated Hamas's action plan and concluded that Hamas was incapable of implementing it. But a female intelligence analyst warned in July that Hamas was conducting round-the-clock, high-intensity military training that looked similar to that of the "Wall of Jericho" program.
It seems that Israeli intelligence needs to do a good job of internal investigation and solve the problem of negligence. This may serve as a lesson to avoid future tragedies from happening again.
