Common Questions

What was the Twelve-Day War?: The Twelve-Day War was a twelve-day conflict in June 2025 between Israel and Hezbollah, fought across southern Lebanon and northern Israel. It killed 1,190 people and ended with a US-brokered Ceasefire.Source: France 24 / Lowdown
How did the Twelve-Day War affect Israel's missile defences?: Israel entered the 2026 Iran conflict critically depleted of Ballistic missile interceptors as a result of the June 2025 fighting. US officials reported Israel was running low on Arrow and David's Sling stocks before the current war began.Source: Semafor / US officials
Why did Iran reject a ceasefire in 2026 citing 2025?: Iranian officials told NBC News and Al Jazeera that the June 2025 Ceasefire was a strategic error: it gave the US and Israel eight months to rearm and prepare the 2026 campaign. Tehran concluded another pause would repeat that mistake.Source: NBC News / Al Jazeera
How many people died in the Twelve-Day War compared to the Iran conflict?: The Twelve-Day War killed 1,190 people over twelve days. By contrast, one week of Israeli airstrikes in the 2026 Iran conflict killed more people in Iran alone than the entire Twelve-Day War combined.Source: France 24
Did the June 2025 ceasefire hold before the 2026 Iran war?: The Ceasefire held for roughly eight months before the wider Iran-Israel-US conflict erupted in late February 2026. During that period the UAE-Iran commercial relationship remained intact, but it collapsed when Iran struck a Dubai consulate in March 2026.Source: Lowdown

Background

The Twelve-Day War was an Israel-Hezbollah conflict fought across twelve days in June 2025, centred on southern Lebanon and northern Israel. Israeli strikes dismantled Hezbollah command nodes and air-defence infrastructure; Hezbollah fired rockets and drones deep into Israeli territory. The fighting ended with a US-brokered Ceasefire that left both sides claiming operational success but physically depleted. The conflict killed 1,190 people.

The war cast a long shadow over the Iran conflict that erupted in February 2026. Israel entered that new campaign critically short of Ballistic missile interceptors, with Arrow and David's Sling batteries run down from the June 2025 fighting. Iran rejected a fresh Ceasefire in 2026, officials explicitly citing the June 2025 pause as a strategic error that gave the US and Israel eight months to rearm.

The Twelve-Day War also reshaped Gulf diplomatic assumptions. The conflict left UAE-Iran commercial channels intact, preserving a buffer that collapsed when an IRGC drone struck the US consulate in Dubai in March 2026. The June 2025 Ceasefire is now read by Tehran as proof that ceasefires enable adversary rearmament, hardening Iranian resistance to any diplomatic pause in the current war.

How the World Sees Them

Iran

Tehran publicly backed Hezbollah but later judged the June 2025 ceasefire a strategic blunder: it gave the US and Israel eight months to rearm and prepare the 2026 campaign. Iran cited this lesson explicitly when rejecting a fresh ceasefire offer.

Israel

Israel launched the offensive to degrade Hezbollah command capacity and buy breathing space on the northern front before a wider war. The depleted interceptor stocks that resulted proved a critical vulnerability when Iran launched massed ballistic salvos in 2026.

Lebanon

Lebanon bore the civilian cost most heavily, with southern communities displaced and infrastructure struck across the twelve days of fighting. When the wider conflict resumed in March 2026, a further 30,000 people were displaced within days.

Hezbollah

Hezbollah absorbed significant command losses but preserved its rocket arsenal and political standing across Lebanese territory, claiming the ceasefire as a strategic hold. Israeli intelligence assessed its residual offensive capability remained constrained as the 2026 conflict opened.

United States

Washington brokered the June 2025 ceasefire and used the resulting eight-month window to coordinate joint target planning with Israel. The pause provided the intelligence and logistics runway that underpinned Operation Epic Fury in February 2026.
