What happened, yesterday

The story

The Middle East remains on edge as the United States executed its tenth consecutive night of airstrikes against Iran, targeting various provinces, including one hosting Iran's only operational civilian nuclear power plant. These strikes follow recent Iranian attacks on US assets in Kuwait and Bahrain, and Jordan's interception of Iranian drones. A tanker in the Strait of Hormuz was also reportedly struck, forcing its crew to evacuate, further highlighting the ongoing maritime risks. Despite the escalating military actions, diplomatic channels remain active. Iran's Foreign Ministry spokesman, Esmaeil Baghaei, confirmed Tehran has received new mediation proposals from Qatar and Pakistan aimed at de-escalating the conflict. US Secretary of State Marco Rubio reiterated Washington's openness to a diplomatic solution, contingent on Iran's behavior. Meanwhile, Israeli intelligence indicates Iran moved thousands of uranium-enrichment centrifuges into fortified tunnels in Pickaxe Mountain after the June 2025 conflict, raising concerns about its nuclear program. This suggests a hardening of positions on both military and nuclear fronts, even as mediators press for a truce.

Three ways this might unfold

A 10-day ceasefire leads to renewed commitment to a broader peace framework. ~15%

If mediators like Qatar and Pakistan successfully broker a verifiable ceasefire, and both the US and Iran commit to serious negotiations on nuclear and regional security.

  • The Strait of Hormuz would see consistent, unimpeded shipping.
  • US forces in the region would reduce their operational tempo.
  • Iran would halt retaliatory strikes on US bases and regional allies.
  • Discussions on Iran's nuclear program would resume with international oversight.
  • Regional tensions would noticeably decrease, potentially opening avenues for broader dialogue.
  • The US would likely offer some sanctions relief in exchange for verifiable commitments.
  • Israel might pause its calls for further military action against Iran's nuclear infrastructure.

Continued strikes and retaliations spiral into direct, widespread military confrontation. ~45%

If the ongoing US strikes expand to critical Iranian infrastructure and Iran launches direct, large-scale attacks on US or Israeli territory.

  • Iran would likely attempt to completely close the Strait of Hormuz, causing severe shipping disruptions.
  • US and Israeli military operations would intensify, potentially involving ground assets.
  • Iranian proxy groups would activate across the region, targeting US and Israeli interests.
  • Numerous G20 nations, particularly energy importers, would face significant economic shocks.
  • Casualties on all sides would increase substantially.
  • International diplomatic efforts would likely fail to contain the conflict.
  • Iran's nuclear program could accelerate without international monitoring.
  • Regional alliances would be tested, with potential for new actors to be drawn in.

The current pattern of targeted strikes and retaliations continues without a clear resolution. ~40%

If neither side achieves a decisive military advantage and diplomatic efforts remain insufficient to bridge fundamental disagreements.

  • Sporadic US airstrikes on Iranian military targets would persist.
  • Iran would continue to launch retaliatory attacks on US bases and commercial shipping.
  • The Strait of Hormuz would remain a high-risk zone for maritime traffic.
  • Casualties among US service members and regional forces would continue to mount.
  • International mediators would persist in offering truce proposals, but without lasting success.
  • Iran would likely continue its nuclear activities, potentially increasing enrichment levels.
  • The risk of miscalculation leading to broader conflict would remain high.
  • Regional economic stability would be undermined by persistent uncertainty.

Threads worth pulling

What others are saying

The Soufan Center. It seems unlikely that Iran will distance itself from its proxy network, which the regime views as an extremely valuable form of strategic depth, regardless of negotiation outcomes.

Carnegie Endowment for International Peace (Jim Lamson). In an interview, Jim Lamson discussed the ongoing regional conflict and saw an "unclear picture when it comes to winners and losers."

Stimson Center (Christopher Preble). The conflict has demonstrated the limits of relying solely on air power, suggesting that military solutions alone may not be sufficient for resolution.
