How Israel defeated Hezbollah in only a few weeks:
17-18 September: Pager and walkie talkie operations cause 3500+ casualties (99% injuries of varying magnitude) and plunged Hezbollah into chaos due to confusion and loss of communications network.
20 September: Ibrahim Aqil, head of Redwan Forces, was injured in the attack but released from hospital on 20th September and met with 10-15 Redwan Forces commanders in an underground bunker on the same day to discuss a response. Israel bombed the bunker and killed everyone inside, taking out the entire leadership of the Redwan Forces.
23-30 September: Israel dramatically escalates the war by starting an extremely intense mass carpet bombing campaign across all of Lebanon, with 300+ airstrikes per day, causing mass displacement and killing 800+ and injuring 4000+ Lebanese people (mostly civilians).
27 September: Hassan Nasrallah met with Ali Karaki and other top officials in Hezbollah's underground HQ in Beirut. Israel dropped 200 bombs in the span of seconds, razing several massive residential blocs to the ground, and killing everyone in the HQ (and dozens of civilians), plunging Hezbollah into leadership crisis.
28 September: Nabil Qaouk, head of Hezbollah's preventive security unit, was killed in an Israeli airstrike.
3 October: Hashem Safiedin (the de facto leader of Hezbollah after Nasrallah was killed) and other key leaders meet in an intelligence bunker to attempt to reorganise the group, but Israel drop 73 tons of bombs (equivalent to 150 Iskander ballistic missiles) on the bunker, killing them all, hugely escalating Hezbollah's leadership crisis.
7 October: Suhail Husseini, head of Hezbollah's logistics, was killed in an Israeli airstrike, the 5th Jihad Council member killed in only a few weeks.
October-November: Local Hezbollah units in the south continued to fight and resist the Israeli invasion, with decent success but at huge cost, and rocket units in the north also continued to operate independently to central command, but with less organisation and intensity than planned.
20-21 October: Israel further escalates its war against Hezbollah and the Lebanese people by targeting the Al-Qard banks associated with Hezbollah, practically the only remaining financial safe haven in Lebanon after its banks went bankrupt years before, bombing dozens of the banks across Lebanon and attempting to destroy their cash reserves held on behalf of ordinary Lebanese people.
26 November: Lebanese government (on behalf of Hezbollah) agrees to ceasefire with Israel.
