What happened, yesterday

The story

The Middle East is seeing a notable increase in US military posture, with American defense officials initiating a significant movement of personnel, combat aircraft, and specialized medical teams to the region. This deployment provides President Donald Trump with enhanced strategic flexibility as his administration evaluates expanding military action against Iran. Simultaneously, US Central Command has confirmed a twelfth consecutive night of strikes against Iranian military targets, aiming to degrade Iran's ability to threaten commercial shipping. The use of a B-1 long-range bomber in a strike earlier this week signals a significant escalation in the US campaign. Further complicating regional stability, Iran-backed Houthi rebels claimed attacks on two Saudi oil tankers in the Red Sea, threatening the Bab al-Mandab Strait and potentially creating a second maritime chokepoint alongside the Strait of Hormuz. Diplomatic efforts to de-escalate the conflict remain largely stalled, with the war's cost to the US military now estimated at $37.5 billion.

Three ways this might unfold

A diplomatic breakthrough leads to a new ceasefire and a framework for negotiations. ~15%

If a new memorandum of understanding is successfully negotiated and agreed upon by all parties, potentially through increased mediation.

  • Diplomatic channels via mediators like Pakistan or Qatar become significantly more active.
  • Iran halts all attacks on commercial shipping in regional waterways.
  • The US ceases its ongoing airstrikes against Iranian targets.
  • Regional states engage in direct de-escalation talks to stabilize the security environment.
  • Focus shifts to establishing a long-term regional security architecture to prevent future conflicts.

Escalation broadens with expanded US military operations and direct Iranian retaliation. ~45%

If US military deployments lead to expanded operations, or Iran and its proxies further disrupt maritime trade or target US/allied assets directly.

  • US strikes target deeper into Iran or its nuclear facilities, as previously threatened by President Trump.
  • Iran retaliates directly against US military assets in the region or against key regional allies.
  • The Strait of Hormuz or Bab al-Mandab Strait face prolonged closures, severely impacting global shipping.
  • The regional conflict broadens to include more state actors, increasing the intensity of combat.
  • Increased cyberattacks target critical infrastructure in the US and allied nations.

The current pattern of US strikes and Iranian/proxy retaliations continues without a major shift. ~40%

If the current cycle of US military pressure and Iranian/proxy counter-actions continues without a decisive diplomatic or military development.

  • The US continues targeted airstrikes against Iranian military infrastructure and maritime capabilities.
  • Iran maintains its naval blockade threats and continues to support proxy attacks in the region.
  • Regional states remain on high alert, with continued defensive measures and intercepted projectiles.
  • Diplomatic efforts remain stalled, with mediators unable to achieve significant breakthroughs.
  • Economic pressures on Iran persist due to sanctions and disruptions to trade.

Threads worth pulling

What others are saying

Carnegie Endowment for International Peace (Aaron David Miller). The United States and Iran have moved perilously close to direct clashes as a result of the escalating war in the Middle East and US efforts to defend Israel.

Stimson Center (Leonardo Jacopo Maria Mazzucco). Iranian officials have made it clear they do not intend to restore unrestricted transit in the Strait of Hormuz, seeking a mechanism with Oman to impose 'service charges' on transiting vessels.

Vanda Insight (Vandana Hari). The impact of the war between the United States and Iran on oil-importing nations in Asia could last years or even decades because of these countries' heavy dependence on those imports.
