Internal Brief: Escalation of US-Israel-Iran Confrontation & Outlook for De-escalation

(For internal reference)

As of 12 June, tensions between the United States, Israel and Iran in the Middle East have escalated rapidly, with the regional situation teetering on the brink of all-out conflict. Achieving a short-term ceasefire is proving difficult. A comprehensive report on the overall situation, the positions of the various parties, the knock-on effects and future trends is provided below:

This round of conflict has escalated in stages since early this month. Israel initiated the conflict by launching air strikes against Iranian targets, to which Iran responded with reciprocal strikes. The intensity of clashes between the parties’ proxies and direct confrontations has continued to rise. On the 10th, US forces launched strikes against military facilities on Iranian soil; on the 11th, Iran formally announced the closure of the Strait of Hormuz. The US military briefly planned a large-scale air strike but subsequently called off the operation at the last minute, bringing the regional military standoff to a temporary peak. Although full-scale war has not yet broken out between the three parties, all fronts remain on high alert and sporadic clashes continue.

The positions of the three parties are clearly defined and their stances uncompromising. The US is pursuing a dual strategy of military pressure and diplomatic negotiations: on the one hand, it insists on deploying forces to escort merchant ships through the Strait, denies that the waterway has been blocked, and retains the option of military strikes; on the other hand, it publicly claims to have reached a preliminary consensus with Iran and plans to sign an agreement in the near future, eager to de-escalate the situation and stabilise oil prices. Israel has temporarily suspended proactive offensives but has clearly drawn red lines, firmly opposing the development of Iran’s nuclear capabilities. It harbours dissatisfaction with a potential US-Iran agreement and reserves the right to take unilateral military action. Iran maintains a hardline stance, using the blockade of the Strait as a bargaining chip. It denies that an agreement has been reached, demands the complete lifting of US sanctions, and warns the US and Israel against provoking further conflict.

The escalation of the situation has already had a significant impact on energy supply routes and the crude oil market. The Strait of Hormuz is currently under a de facto blockade, operating in a state of partial closure. Iran is focusing on intercepting large oil tankers, whilst the US military is forcibly ensuring the passage of some vessels, resulting in a significant increase in the risks associated with navigation. Driven by fears of supply disruptions, international crude oil prices have surged sharply in the short term and are currently fluctuating at high levels. The premium resulting from the risk of war persists, with shipping insurance and transport costs rising in tandem.

The United Nations and major powers outside the region have widely called for a ceasefire and mediation. The UN Secretary-General has issued repeated warnings, expressing concern that the spread of the conflict could trigger a global crisis, and has demanded that all parties cease fire and ensure the free passage of international shipping lanes; however, these initiatives lack binding force. China and Russia have maintained a neutral stance in favour of reconciliation, opposing unilateral sanctions and military adventurism, and advocating the resolution of differences through political dialogue whilst upholding normal shipping order. Gulf states, situated on the front line of the conflict, are concerned both about the spread of hostilities and the disruption of oil exports. They are actively engaging in mediation efforts across multiple channels, hoping for a swift de-escalation of the situation.

A comprehensive assessment of the likely trajectory suggests that the situation will remain deadlocked at a high level in the short term. The coming week will be a critical window: if US-Iran negotiations proceed smoothly, the Strait gradually returns to normal passage, and the three parties achieve a phased ceasefire, oil prices are expected to fall accordingly; if negotiations break down and Israel launches further attacks, the conflict is highly likely to escalate, the blockade of the Strait will intensify, crude oil prices will surge sharply, and the Middle East may descend into prolonged conflict. Overall, none of the parties are currently prepared for all-out war, and the probability of a large-scale conflict breaking out in the short term is limited; however, the underlying contradictions remain unresolved, and regional tensions are set to persist for the long term.
