Significant adjustments have recently emerged in U.S. military and diplomatic operations in the Middle East. Since the deployment of the USS Ford in late June 2025, the fleet has been conducting missions in the region for over eight months, setting a rare record for long-term deployment. Simultaneously, the U.S. government has adopted a tougher stance toward Iran, not only rejecting Iranian proposals regarding the reopening of the Strait of Hormuz but also dispatching high-level Treasury officials to conduct multinational lobbying, demanding that European and Middle Eastern nations sever economic and diplomatic ties with Iran. These actions indicate that the U.S. is attempting to consolidate its strategic influence in the Middle East and curb Iran's regional expansion through military deterrence and economic blockade.

According to multiple international media sources, the U.S. Navy is currently taking action to send a second aircraft carrier to the Middle East as reinforcements. This move is viewed as support for existing deployed forces and a response to the increasingly tense situation in the region. Furthermore, high-level U.S. Treasury official Burke has recently visited over 50 countries, spanning Europe and the Middle East, to clearly convey the U.S. position to various governments and demand that they cease cooperative relations with Iran. These military and diplomatic maneuvers constitute the core of current U.S. policy in the Middle East: limiting Iran's operational space in the region through tangible displays of military force and a global sanctions network.

However, sources differ on the details and impact assessments of these events. Regarding the specifics of the military deployment, it remains unclear how long the second aircraft carrier will remain in the region; this uncertain deployment duration has subjected the crew to immense psychological and physical stress. Euronews cited U.S. lawmakers stating that due to the prolonged deployment of the USS Ford, there have been eight attempted suicides among the crew, indicating that the mental health impact on U.S. service members caused by long-term stationing has become a focus of congressional concern.

Additionally, former Iranian President Ahmadinejad adopted a dismissive attitude in an interview, stating that Iran does not perceive U.S. military actions as a direct threat. He criticized past negotiations between the two sides for failing to resolve historical issues, highlighting a significant gap in how the U.S. and Iran perceive the current tensions.

These actions have had profound effects on industries and policies in the Middle East. U.S. lobbying for economic sanctions against Iran has directly impacted energy trade and financial transactions in the region. For Persian Gulf nations dependent on the Strait of Hormuz for oil transport, the U.S. refusal to negotiate with Iran regarding the opening of the strait has increased shipping risks and insurance costs. Furthermore, the military pressure of long-term deployment not only affects the morale of U.S. troops but also makes it difficult for host nations to balance their relationships with the U.S. and Iran.

At the policy level, the pressure from the U.S. for countries to choose sides has forced Middle Eastern and European nations to make difficult choices between economic interests and the U.S. security umbrella, creating potential instability for regional security and supply chains.

Despite the U.S. taking a hardline stance, there are differing views on the effectiveness of such strategies. Some argue that military reinforcements and sanctions are necessary means to contain the Iranian threat and effectively prevent the expansion of regional conflict. However, another school of thought fears that excessive military pressure could prove counterproductive, leading Iran to take more aggressive responses and even risking accidental escalation. Furthermore, regarding the mental health of U.S. troops, critics point out that if the burnout and psychological crises caused by long-term deployment are not addressed, the effectiveness of military deterrence will be significantly diminished.

Therefore, the outside world should not over-interpret the strategic significance of a single military action, but rather view it as an expedient measure by the U.S. to maintain regional influence under multiple pressures, rather than a permanent solution.

Key areas for future observation include the deployment schedule and mission objectives of the second U.S. aircraft carrier, as well as specific measures taken within the U.S. military to improve the mental health of service members. At the same time, the degree to which various countries cooperate with the U.S. Treasury's sanctions lobbying will determine the effectiveness of the U.S. economic blockade on Iran. Additionally, whether Iran will take more aggressive countermeasures regarding shipping rights in the Strait of Hormuz, and whether there remains room for renewed dialogue between the U.S. and Iran, are critical variables affecting the future development of the Middle East situation. The international community will continue to monitor whether U.S. military deployments in the Middle East will further escalate and the long-term impact of these actions on global energy markets and the regional security architecture.
