〔Overnight Brief〕Hormuz Truce Expiry Turns Military: Trump Threatens to Bomb Oman, Iran Seizes UAE-Linked Tanker, WTI Breaks $84 as Pentagon Doubts Its Own Plans – Crossings Fall

1. Overnight Arc: MOU Expiry Without a Deal

• The 60-day negotiating window set by the June 17 US-Iran memorandum expired on Aug 17 with no substantive progress, as serious differences over the Strait of Hormuz remained ^[1][2].
• President Trump says the US will not seek to extend the memorandum ^[1], and he repeated his "idea" of declaring the Strait of Hormuz US territory, insisting the waterway is open and oil prices are falling ^[3].
• Iran has decided to shift from a defensive to a "fully offensive" policy because of the deadlock, a senior Iranian official told Reuters ^[4], and will escalate tensions and launch an attack if the US does not implement the interim deal fully within weeks ^[5].
• Trump told Iran to surrender ^[6].

2. Military and Law-Enforcement Actions on the Water

• **[ESCALATED] CENTCOM:** The USS Mason (DDG 87) is enforcing "America's steel wall blockade" against Iran; as of Aug 17, forces had redirected 64 commercial vessels, disabled 3, and boarded 2 ^[7].
• **[NEW] Iran's seizure:** A tanker belonging to a UAE company was intercepted near Qeshm Island, according to Iran's Fars News, and Iranian officials said all vessels must use Tehran-designated routes ^[8][9].
• **[NEW] Trump's Oman threat:** In parallel talks between Iran and Oman on the strait ^[10][11], Trump warned: "If Oman gets in the way, we'll bomb the shit out of them" ^[11], reported by Bloomberg and Reuters as well ^[2][6].
• **Houthi side-action:** Yemen's Houthis attacked a Saudi military ship and four escort vessels off Mocha with missiles, per the group's military spokesperson Yahya Saree ^[12].

3. Oil Market and Shipping Read

• **Prices:** WTI broke above $84/bbl for the first time since July 31, up 2.93%; Brent rose 3% to $89.83 ^[13].
• **Supply:** Energy Secretary Chris Wright said the US is shipping 8-9 million barrels per day in connection with the military action ^[14]; Saudi Arabia is offering oil from off the Oman coast, a sign it may be shuttling more barrels through Hormuz like the UAE ^[15].
• **Flows:** Strait of Hormuz crossings are falling as the ceasefire expires ^[16], and Investopedia flags how chokepoints like Hormuz could strangle economies worldwide ^[17].
• **Counter-signal:** Politico reports Trump's rosy claims about Hormuz collide with tanker data ^[18].

4. The Pentagon's Doubt and the Political Bind

• **[NEW] (single-source / unverified):** A regional intelligence source told Iran's Press TV that the Pentagon has concluded no existing military plan can guarantee safe passage through the Strait or stable energy supplies, exposing a strategic impasse in Washington ^[19].
• **Scoping down:** CNN reports the US government has further shrunk its war goals against Iran; with midterms approaching, the Iran campaign is hurting Republican prospects, and Trump has approved millions from his political action committee for GOP candidates ^[20].
• **New leverage:** Michael Allen (managing director, Beacon Global Strategies; former Bush national security aide) says Iranians feel they have "a lot of new leverage" they lacked before US-Israel strikes ^[21].

5. Contradictions and What Decides Next

• **Contradictory narratives:** Trump says the strait is open and oil is falling ^[3], while tanker data reportedly show otherwise ^[18] and WTI/Brent rallied overnight ^[13]. CENTCOM touts enforcement ^[7] while the Pentagon reportedly doubts its own plans ^[19].
• **Diplomatic channel:** A possible deal between Iran and Oman could reopen Hormuz for shipping ^[22]; Kushner says dialogue with some Iranians is deeper than ever and Trump is patient on an Iran agreement ^[23], and Kushner is expected to meet Israeli Prime Minister Netanyahu ^[24].
• **Iran's denial:** Iran says it has no intelligence that attacks against Iraqi Kurdistan were launched from its territory ^[25].
• **Source-quality notes:** The Pentagon assessment is a single-source item via Press TV ^[19]; the tanker seizure details rely on Fars News ^[9]; hold these against oil prices and CENTCOM counts ^[13][7].
• **Falsifiable tests:** Watch whether seizures continue, whether WTI holds above $84, and whether the Iran-Oman channel produces a reopening deal or collapses into further threats ^[8][13][22].
