What happened, yesterday

The story

The rhetoric between Washington, Jerusalem, and Tehran intensified over the weekend, with both sides signaling hardened positions. Israeli Prime Minister Benjamin Netanyahu publicly stated that further military action against Iran is not off the table, describing the Iranian threat as a 'cancer' that requires removal. This stance was echoed by US President Donald Trump, who claimed the US had militarily defeated Iran and destroyed its nuclear capacity, yet suggested American forces might remain in the Middle East longer to prevent any rebuilding. In response, Iran's hardline media, like the Kayhan newspaper, issued a direct threat to target Israeli nuclear facilities if the US were to attack Iran's 'Pickaxe Mountain' site. Simultaneously, Iran's Supreme National Security Council head, Mohsen Rezaei, deemed the latest US response to Tehran's proposal for reopening the Strait of Hormuz 'insufficient,' signaling ongoing diplomatic deadlock. These exchanges unfold as Iran claims to have established a new order for shipping in the Persian Gulf, further complicating international navigation. The diplomatic impasse is stark, with a growing internal debate within Iran between those advocating for de-escalation and hardliners pushing for continued confrontation.

Three ways this might unfold

A limited, conditional de-escalation agreement is reached, focusing on shipping and a partial return to nuclear talks. ~25%

If diplomatic channels, particularly those mediated by Pakistan and Qatar, gain traction and both the US and Iran see a mutual benefit in de-risking the Strait of Hormuz,

  • Iran might agree to international oversight of shipping lanes in exchange for some sanctions relief.
  • The US could offer a temporary pause in certain sanctions, allowing limited Iranian oil exports.
  • Indirect talks on nuclear parameters could resume, albeit without immediate commitments to a full deal.
  • Regional states like Saudi Arabia may see a decrease in Houthi-led attacks as a goodwill gesture from Iran.
  • Israel might temporarily halt further strikes on Iranian targets, awaiting outcomes of renewed diplomatic efforts.
  • The internal Iranian debate between hardliners and pragmatists could lean slightly towards diplomatic engagement.

Escalation to direct military confrontation between the US/Israel and Iran, potentially involving strikes on critical infrastructure. ~45%

If Iran acts on its threats against Israeli nuclear sites or regional data centers, or if US/Israeli military action targets 'Pickaxe Mountain' or other key Iranian facilities,

  • US and Israeli forces could launch targeted strikes on Iranian nuclear or military infrastructure.
  • Iran may retaliate with missile or drone attacks against US bases or Gulf allies, as threatened by Mohsen Rezaei.
  • Further disruption to shipping in the Strait of Hormuz and other waterways is highly probable.
  • A broader regional conflict involving proxies and direct state-on-state action would become more likely.
  • G20 nations would likely face increased economic fallout, including higher energy prices and inflation.
  • Internal security in Iran could deteriorate rapidly, leading to widespread civil unrest.

Continued diplomatic stalemate and low-level military friction, with no significant breakthrough or major escalation. ~30%

If neither side is willing to make substantial concessions, but also seeks to avoid full-scale war, leading to a continuation of current tensions,

  • Iran will continue its ballistic missile production and restoration efforts at a slow pace.
  • The US will maintain its naval blockade and economic pressure, monitoring Iranian activities closely.
  • Occasional, localized maritime incidents or proxy attacks will persist without leading to a wider conflict.
  • International calls for diplomacy from countries like Egypt and Turkey will continue without yielding concrete results.
  • The internal debate within Iran regarding its foreign policy direction will remain unresolved.
  • G20 discussions will continue to highlight the economic instability caused by the ongoing war without immediate solutions.

Threads worth pulling

What others are saying

Carnegie Endowment (Karim Sadjadpour). A net assessment of Iran's nearly half-century campaign against Israel concludes it has inflicted more suffering on Palestinians, Arabs, and Iranians than on Israelis, with the chief political beneficiary being the Israeli right.

The Soufan Center (IntelBrief). Great power competition among the U.S., Russia, and China has fueled Iran's war effort from its inception.
