I have been researching the military deployment and development trends of the US military recently, as these are the most critical and direct factors affecting the current market trend. I am not a macro analyst, I am just an ordinary trader. I must use the information I can gather as a reference for my future trading decisions. Regarding the analysis of war dynamics, I also asked Grok and Chattpt separately. Based on the current situation, if Iran does not make substantial concessions to the "15 Demands" after the ultimatum expires on April 6th, both AI models believe that the probability of the United States expanding its air strike/strike range is high (over 50%), while the probability of seizing/controlling Halk Island is low (around 20%). I have summarized his main considerations, including the following: 1. Halk Island is too close to the mainland and is completely covered by Iran's saturated firepower, making it easy to become a live target after capturing the island, which goes against the modern US military's concept of "zero casualties" or "non-contact combat". 2. Probably, the rate will cause economic backbiting. As long as the conflict expands, the impact of soaring oil prices on US debt and US stocks is real, which is a huge resistance for Trump. 3. Occupying is easy, but withdrawing is difficult. Trump is more like a "businessman". He doesn't want the United States to be dragged into a long-term quagmire. But personally, I don't think the probability of ultimately "taking over the island" will be so low. I am looking at the micro level dynamics of military forces: Firstly, in the tactical manual of the US military, the 82nd Airborne Division is used for "knocking on doors" rather than "violating or defending". If it's just to expand the long-range strike range, deploying a few air force squadrons or adding destroyers (fully equipped launch units) would suffice. If everyone has come, it means that the plan for seizing the island (or other key facilities) has changed from a backup to a pending execution. Secondly, if it is to expand air strikes, it can only be bombing, but cannot achieve "closure" or "takeover"; It also forces Iran to adopt self destructive scorched earth tactics and long-term harassment. But if it is possible to physically take over (such as closing the pumping station and loading facilities on the island), the US will have the largest physical pledge on the negotiating table (with the largest bargaining chip). Once Iran does not bow down after the ultimatum day (which currently appears to be very tough), in order to maintain the credibility of its leader, it is necessary to take an intermediate action that is heavier than airstrikes but lighter than a full-scale war; And taking the island is the most perfect middle option. I have read many foreign analysts who believe from a "rational game" perspective that if Iran adopts asymmetric attacks on oil fields in other parts of the Middle East, it will hinder the actions of the US military. But I still believe that the current military posture of the US military is precisely to prepare for a strong counterattack. Perhaps this time, the US may no longer be afraid of short-term oil price surges. If they can exchange a week of pain (seizing islands and physically blockading the strait) for the dominance of energy exports to Iran for the next 20 years, they may consider this price worth it.
