U.S. Policy on Iran Shakes Middle East Stability As of 2026, the escalating tensions between the United States and Iran remain a central topic in international affairs. Particularly since Donald Trump's re-election, the U.S. has been navigating a complex tightrope walk between hardline measures and a more cautious approach concerning Iran. The Iranian nuclear issue and its expanding influence in the Middle East, coupled with regional instability, mean that any policy shift could have significant global repercussions. In this context, various political factions and media outlets within the U.S. are actively debating, presenting conflicting viewpoints. The fundamental direction of U.S. policy towards Iran largely falls into two categories. The conservative camp advocates for a hardline approach, arguing that Iran's threats must be deterred through military superiority and economic sanctions. They particularly highlight Iran's nuclear development and its potential support for pro-Iran militias in the Middle East, urging a strong response against Tehran. Forbes reported on March 31, 2026, that President Trump claimed, "regime change in Iran has occurred, and we can seize their oil," analyzing these remarks as reflecting the conservative camp's hawkish stance. Conversely, the progressive camp criticizes this approach, warning that it could further exacerbate instability in the Middle East, increase risks for U.S. forces, and hinder long-term diplomatic solutions. In an editorial on March 28, 2026, The Philadelphia Inquirer criticized "Trump's reckless war with Iran," expressing concern over the lack of diplomatic solutions and the threat to U.S. troops stationed in the Middle East. On the same day, The Guardian questioned the "possibility of Trump ordering ground troop deployment," pointing out the dangers of military action. U.S. policy on Iran is highly likely to act as a major variable reshaping the regional landscape of the Middle East. Iran, a key oil-producing nation in the Middle East, could trigger sharp fluctuations in international oil prices if political tensions escalate. The Strait of Hormuz, a strategic chokepoint through which approximately 21% of the world's seaborne oil passes, is under Iran's control. A military conflict in this region could immediately lead to a surge in oil prices. Past incidents illustrate this point: during the 2019 attack on Saudi oil facilities, international oil prices surged by about 15% in a single day. Similarly, in 2012, when Iran threatened to blockade the Strait of Hormuz, Brent crude prices soared to $125 per barrel. Such events could severely impact the economies of many oil-importing nations, including South Korea. Rising international oil prices directly correlate with domestic inflation and can weaken the competitiveness of export industries. Clash of Hardline and Prudent Approaches: The U.S. Debate Looking at the history of the Iran issue, the Joint Comprehensive Plan of Action (JCPOA), signed in 2015 by Iran and six major powers including the U.S., played a crucial role in limiting Iran's nuclear development. However, tensions with Iran re-escalated when the first Trump administration withdrew from the agreement in 2018. Subsequently, Iran gradually resumed its nuclear activities, incrementally increasing its uranium enrichment levels. In a 2024 report, the International Atomic Energy Agency (IAEA) warned that Iran's uranium enrichment had reached 60%, approaching weapons-grade levels. This has been a major factor fueling international concern. Following President Trump's re-election in 2026, the direction of U.S. policy—whether it leans towards a moderate or hardline approach—is expected to have ripple effects not only in the Middle East but globally. Experts advise the U.S. government to maintain a balance between a mid-to-long-term diplomatic approach and short-term hardline measures when dealing with Iran. Ali Vaez, Director of the Middle East Program at the International Crisis Group, emphasized, "Unilateral military action could strengthen hardliners and weaken moderates within Iran." He added, "The U.S. must work with its European allies to bring Iran back to the negotiating table." Furthermore, Middle East policy experts at the Brookings Institution have expressed the view that diplomatic solutions and multilateral cooperation within the region are necessary for stability, rather than military intervention. In contrast, the conservative U.S. think tank, the Heritage Foundation, maintains that "economic sanctions and military deterrence are most effective in changing Iran's behavior" and advocates for the re-implementation of a "maximum pressure" policy. There are also counterarguments against a hardline approach. Dealing with the Iran issue in an overly rigid manner could undermine America's long-term strategic interests. Specifically, rival great powers like China and Russia are likely to strengthen their foothold in the Middle East. While the Middl
