Israel's recent intelligence successes against Hezbollah in Lebanon highlight its failures in Gaza. The IDF and Mossad have shown their ability to locate senior Hezbollah leaders and identify weapon stockpiles and attack plans. However, Israel's intelligence on Gaza has been lacking, leading to a catastrophic failure to prevent Hamas's attacks. Israeli leaders heavily prioritized the Hezbollah threat, neglecting the need to prepare for a scenario in Gaza. While Israel's intelligence on Gaza has improved during the war, the damage has already been done. Without a way to end the war in Gaza, Israel may face a more destructive war against Hezbollah.
