U.S

For: Threat causes temporary jitters, not lasting price jump

• The concentration of U.S. refueling tankers indicates sustained U.S. military operations requiring extended airtime over the Strait of Hormuz. High refueling tanker concentration indicates sustained US air operations and commitment to maintaining control, which directly supports the hypothesis that US military presence can deter and prevent Iranian closure enforcement. 1 source, analysis

For: Strait closure forces oil prices sharply higher

• The concentration of U.S. refueling tankers indicates sustained U.S. military operations requiring extended airtime over the Strait of Hormuz. 1 source, analysis
• Iranian Revolutionary Guard Corps announced closure of the Strait of Hormuz until further notice. 1 source, primary
• Iranian announcement of closure of the Strait of Hormuz represents threat to global maritime commerce and oil supply chains dependent on the waterway. 1 source, analysis
• The presence of Boeing E-3B Sentry early warning aircraft over the Strait of Hormuz suggests U.S. establishment of comprehensive air command and control structure for sustained operations. 1 source, analysis
• The U.S. and Iran have entered a cycle of tit-for-tat military escalation with mutual announcements of strikes and closures. 1 source, analysis

For: Escalation spirals into major price shock

• The U.S. and Iran have entered a cycle of tit-for-tat military escalation with mutual announcements of strikes and closures. Direct confirmation of tit-for-tat cycle is core to the escalation spiral hypothesis; this evidence settles whether the precondition exists. 1 source, analysis

Supporting evidence

• United States Central Command announced third round of strikes against Iranian military targets following Iranian attack on container ship M/V GFS Galaxy. CENTCOM's announcement of a third strike round following Iran's container ship attack directly exemplifies the trading-blows-but-restraint pattern: action-response cycle without escalation to wider conflict. 1 source, named source
• The U.S. and Iran have entered a cycle of tit-for-tat military escalation with mutual announcements of strikes and closures. Direct description of tit-for-tat cycle with mutual announcements precisely matches the trading-blows-while-signaling hypothesis. 1 source, analysis

For: US struck back after Iranian attack or credible threat

• The U.S. and Iran have entered a cycle of tit-for-tat military escalation with mutual announcements of strikes and closures. Explicitly characterizes the pattern as tit-for-tat escalation in which each side responds to the other's move, directly supporting the reactive-response framing of the hypothesis. 1 source, analysis
• Iranian Revolutionary Guard Corps announced attack on ships in the Strait of Hormuz, claiming they ignored warnings. IRGC announcement of attacks on ships and closure of the waterway directly provides the Iranian hostile action that the reactive hypothesis requires as the trigger for US response. 1 source, primary
• Iranian Revolutionary Guard Corps announced closure of the Strait of Hormuz until further notice. IRGC closure of the Strait of Hormuz is a hostile act that directly instantiates the 'credible threat' the reactive hypothesis identifies as justifying US response. 1 source, primary
• United States Central Command announced third round of strikes against Iranian military targets following Iranian attack on container ship M/V GFS Galaxy. CENTCOM announcement explicitly frames strikes as following Iranian attack on ship, directly matching the reactive-response hypothesis and distinguishing it from preventive-action framing. 1 source, named source
• Iranian announcement of closure of the Strait of Hormuz represents threat to global maritime commerce and oil supply chains dependent on the waterway. Iranian closure of the Strait of Hormuz is framed as a hostile threat to global commerce, providing the specific 'credible threat' that justifies US reactive strike under the hypothesis. 1 source, analysis

For: US aimed to prevent future Iranian action, not respond to past attack

• The concentration of U.S. refueling tankers indicates sustained U.S. military operations requiring extended airtime over the Strait of Hormuz. Concentration of refueling tankers specifically indicates sustained operations requiring extended airtime, which discriminates preventive sustained campaign from reactive single-night strike. 1 source, analysis

For: US strike claims are broadly accurate

• Flight tracking data from Flightradar24 recorded 18 U.S. military aircraft flying over the Strait of Hormuz and surrounding waters since dawn on Sunday. One hypothesis considered: FlightRadar24 tracking of 18 military aircraft over the Strait directly confirms the documented air presence cited as evidence for the accuracy hypothesis, discriminating it from claims of fabricated or exaggerated operations. 1 source, verified

For: US can sustain strikes; both sides tolerating higher escalation risk

• The concentration of U.S. refueling tankers indicates sustained U.S. military operations requiring extended airtime over the Strait of Hormuz. Tanker concentration interpreted as indicator of sustained extended-airtime operations directly affirms hypothesis claim that refueling architecture reflects 'sustainable operational capability.' This causal interpretation proves sustained posture over depleting-resources alternative. 1 source, analysis
• The 18 U.S. military aircraft distributed their activities among refueling tankers, maritime patrol and reconnaissance aircraft, and early warning aircraft. Specific distribution of aircraft roles (refueling, maritime patrol, early warning) proves coordinated specialized architecture. This functional diversity directly supports hypothesis claim of premeditated sustainable capability over ad-hoc desperation. 1 source, verified
• The presence of Boeing E-3B Sentry early warning aircraft over the Strait of Hormuz suggests U.S. establishment of comprehensive air command and control structure for sustained operations. E-3B presence as air-command-and-control directly instantiates hypothesis claim of 'sustainable operational architecture' with 'specialized support aircraft.' This interpretation discriminates premeditated-capability hypothesis from forced-escalation alternatives. 1 source, analysis
• The tracked aircraft included 1 Boeing P-8A Poseidon and 1 Boeing E-3B Sentry early warning aircraft. P-8A (maritime patrol) and E-3B (air command-and-control) directly embody hypothesis claim of specialized support aircraft indicating 'sustainable operational architecture.' These specific platforms discriminate sustained-capability hypothesis from forced-desperation scenarios. 1 source, verified
• The U.S. and Iran have entered a cycle of tit-for-tat military escalation with mutual announcements of strikes and closures. Tit-for-tat cycle with mutual announcements directly confirms hypothesis characterization of 'reciprocal declarations' and 'calculated escalation theater.' Proves neither side hiding capabilities or showing panic. 1 source, analysis

For: Current pace unsustainable; forces will exhaust within weeks

No strong supporting evidence

For: Both sides planning for prolonged measured strikes, not all-out war

• United States Central Command announced third round of strikes against Iranian military targets following Iranian attack on container ship M/V GFS Galaxy. CENTCOM's public announcement of strike sequence and numbers, paired with apparent Iranian response cycle, directly matches the managed-crisis template of controlled escalation rather than all-out war. 1 source, named source
• The U.S. and Iran have entered a cycle of tit-for-tat military escalation with mutual announcements of strikes and closures. Tit-for-tat escalation with mutual announcements is the defining feature of the managed-crisis model; this pattern specifically discriminates it from all-out war or imminent exhaustion scenarios. 1 source, analysis
