What happened, yesterday

The story

The Middle East remains a crucible of escalating tensions as the United States conducted its tenth consecutive night of airstrikes against Iran. These sustained attacks follow the deaths of US service members and are aimed at degrading Iran's ability to target commercial vessels in the Strait of Hormuz. In response, Iran's Revolutionary Guard Corps launched retaliatory attacks on US military sites in Kuwait and Bahrain, and a tanker was struck in the vital Strait of Hormuz, forcing its crew to abandon ship. The current military actions occur after the collapse of an interim Memorandum of Understanding (MOU) that aimed to pause fighting and restart nuclear negotiations. Despite the military escalation, diplomatic channels remain open, with Iran's Interior Minister traveling to Pakistan for talks. US Secretary of State Marco Rubio also stated that the US remains open to negotiations, though Iran's behavior continues to be a concern. The ongoing conflict and disruption in the Strait of Hormuz continue to raise concerns about regional stability and global trade.

Three ways this might unfold

A new, broad diplomatic agreement is reached between the US and Iran, leading to de-escalation. ~20%

If a new comprehensive agreement is reached covering nuclear, sanctions, and regional security, with strong verification mechanisms,

  • Major sanctions on Iran are lifted, allowing its oil to return to global markets.
  • Iran agrees to full international monitoring of its nuclear program.
  • Iran reduces support for regional proxy groups, decreasing attacks on US and allied interests.
  • The Strait of Hormuz reopens fully and sustainably, easing shipping concerns.
  • Regional security dialogues increase, fostering greater stability.
  • The current US military presence in the region may be re-evaluated.
  • Economic relief for Iran could lead to internal reforms.

Military actions escalate significantly, leading to a wider regional conflict. ~50%

If either the US or Iran conducts a strike that crosses a new red line, or if a critical incident occurs in the Strait of Hormuz,

  • Direct military confrontation between the US and Iran intensifies.
  • The conflict expands to include more regional actors, potentially drawing in Gulf states.
  • The Strait of Hormuz faces a full and prolonged closure, severely disrupting global oil supplies.
  • Cyberattacks targeting critical infrastructure in the region and beyond increase.
  • Further US military deployments to the Middle East are likely.
  • Global energy prices surge dramatically due to supply fears.
  • Humanitarian crises in conflict zones worsen significantly.

The current pattern of tit-for-tat military exchanges and limited diplomatic efforts continues. ~30%

If neither side achieves a decisive military advantage and diplomatic efforts remain stalled without a breakthrough,

  • US airstrikes on Iranian targets continue intermittently, met with Iranian proxy attacks.
  • Shipping in the Strait of Hormuz experiences ongoing, unpredictable disruptions.
  • Mediation efforts by countries like Pakistan and Qatar continue without yielding a lasting agreement.
  • Regional tensions remain high, with periodic flare-ups and security alerts.
  • The interim MOU remains collapsed, with no clear path to its revival or replacement.
  • US troop presence in the region remains elevated to deter further Iranian aggression.
  • Economic strain persists for oil-importing nations due to elevated energy prices.

Carnegie Endowment for International Peace (Aaron David Miller). Aaron David Miller noted the recent escalation in the Middle East and discussed whether America is ready to reset its relationship with Israel, and how the war with Iran could shape the region.

Stimson Center (Christopher Preble). Christopher Preble commented that the conflict demonstrates the limits of relying solely on air power, stating that the US military can only accomplish so much with escalating airstrikes.

The Soufan Center. The Soufan Center's analysis suggests that regardless of a deal, Iran will likely continue to cultivate proxy groups as a form of strategic depth, which has not been a part of current negotiations.
