Hamas is on Israel’s doorstep. One would think Israel could better understand what is happening in Gaza and the West Bank, as opposed to 1,000 miles away in Iran. How did Israel not see something this advanced right next door? Some Israeli officials have said they believed Hamas was already deterred by recent Israeli counterterrorism operations, and that the group lacked the capability to launch an attack on the scope and scale of what occurred.

Israel is widely recognized as having highly sophisticated intelligence capabilities, both in terms of its ability to collect information about potential threats within its own country and outside of it. And so as details unfold about the full extent of Hamas’ unprecedented and surprise attack on 20 Israeli towns and several army bases on Oct. 7, 2023, the question lingers: How did Israel fail to piece together clues about this large-scale and highly complex plot in advance?

Israeli intelligence did detect some suspicious activity on Hamas militant networks before the attack, The New York Times reported on Oct. 10, 2023. But the warning wasn’t acted upon or fully understood in its entirety – similar to what happened in the United States shortly before the terrorist attacks on Sept. 11, 2001.

“Intelligence analysis is like putting a thousand-piece jigsaw puzzle together from individual pieces of intelligence every day and trying to make judgments for policymakers to actually do something with those insights,” said Javed Ali, a counterterrorism and intelligence scholar who spent years working in U.S. intelligence.

The Conversation spoke with Ali to try to better understand how Israeli intelligence works and the potential gaps in the system that paved the way for the Hamas incursion.

1. What questions did you have as you watched the attacks unfold?
This took an enormous amount of deliberate and careful planning, and Hamas must have gone to great lengths to conceal the plotting from Israeli intelligence. This plotting may indeed have been hidden as the plot was being coordinated.

Because of the attack’s advanced features, I also thought that Iran almost certainly played a role in supporting the operation – although some U.S. officials have so far said they do not have intelligence evidence of that happening.

Finally, Hamas is on Israel’s doorstep. One would think Israel could better understand what is happening in Gaza and the West Bank, as opposed to 1,000 miles away in Iran. How did Israel not see something this advanced right next door? Some Israeli officials have said they believed Hamas was already deterred by recent Israeli counterterrorism operations, and that the group lacked the capability to launch an attack on the scope and scale of what occurred.
