Snapback and Preemptive Action

In the midst of growing protests around Iran, on January 6, 2026, Iran International reported the following two disturbing developments.

The reactivation of pre-2015 United Nations sanctions through the snapback mechanism in September 2025 has proven difficult to circumvent, constraining access to finance, insurance and energy markets. These constraints have translated into economic pressure.

Iran’s newly formed Defense Council warned on January 6 that the country could respond before an attack if it detected clear signs of a threat, amid rising tensions with the United States and Israel: ‘Any infringement on national interests, interference in internal affairs or action against Iran’s stability will be met with a proportionate, targeted and decisive response... An escalation in threatening language and interventionist conduct that goes beyond verbal posturing may be interpreted as hostile behavior.’

Shahram Kholdi assessed that ‘2026 will test the limits of Tehran’s endurance’. The nuclear conundrum has moved away from center stage. But IAEA still has to deal with it.

‘New war with Israel at any moment’, ‘still digging through rubble’

The news about Iran has taken an ominous tone in the last couple days. Here is some reporting and commentary. Newsweek on August 18, 2025, reported that Yahya Rahim Safavi, senior military adviser to Supreme Leader Ali Khamenei, said ‘ We are not in a ceasefire; we are in a stage of war. No protocol, regulation, or agreement has been written between us and the U.S. or Israel. A new war with Israel could break out at any moment .’ Yonah Jeremy Bob commented in The Jerusalem Post on August 19, 2025, that ‘ Khamenei can either “drink from the poisoned chalice” of diplomatic concessions … or face more airstrikes, possibly next time some targeting him directly ’. Bob also noted that ‘ right now Iran is still digging through rubbl e’. The U.S. attacked Fordow, Natanz and Esfahan on June 22. Two months of digging. No surprise that there has been no public news about that.

Assessing possible outcomes of the snapback mechanism

The initiation by the E3 of the 30-day snapback mechanism in the UN Security Council makes everything more difficult and there is great uncertainty about the outcome. Will it be peaceful with a new nuclear deal with Iran, negotiated by the U.S., endorsed by the UNSC and verified by IAEA, or will Iran withdraw from NPT with further military action by Israel and the U.S.? To perhaps shed a little light on what the outcome will be, here is my analysis of how the players - Iran, U.S. and E3 - may be assessing the acceptability of the range of outcomes. Four levels of acceptability were used: 1 Fully acceptable; 2 Less acceptable; 3 Just acceptable; and 4 Not acceptable. Four near term 30-day outcomes are listed, and two optimistic outcomes with an interim U.S.-Iran agreement reached within a 6-month extension. For the 30-day near term, the best outcome would b...

More on MOABs

MOAB is a 30,000-pound steel-alloy, precision-guided bomb designed to destroy subterranean targets. Its proper name is GBU-57, also known as “bunker buster” or Massive Ordnance Penetrator (MOP). MOP development dates to at least 2002. In 2007, the Air Force said it could penetrate up to 200 feet. The latest version, known as GBU-57E/B, has been in the operational inventory since 2016. In January 2018, the 4th upgrade was completed. Upgrades continue, especially improving the fuse. The number available for operational use is not public; the initial order to Boeing was for 20. In February 2018, more were ordered. Some have been used in tests. The small number of B-2 Spirit stealth bombers are the only aircraft that can deploy MOAB. There are no public reports of MOAB being used in combat. ( But it was reported that one was deployed in Afghanistan .) Much of the impetus for the MOP program was provided by Iran’s push to bury its nuclear enrichment infrastructure deep und...
