From Dominance to Dilemma

The USA After the Iran War

In the late 1800s, the USA emerged as the world’s largest economy after overtaking Britain and maintained its supremacy through its powerful military, strategic global location, and modern technological innovation. The collapse of the USSR in 1991 marked the end of the Cold War and produced the “New World Order”— a unipolar international system dominated by a single superpower: the USA.

This US hegemony has fundamentally shaped how nations interact, trade, and resolve conflicts in the 21st century. US global dominance has rested on three interrelated foundations: financial power, military strength, and technological innovation.

After World War II, the US dollar became the central global currency, as it was directly linked to gold, while other currencies were connected to the dollar. As a result, the dollar emerged as the most trusted and dominant currency in the international system. This monetary supremacy enabled the USA to dominate the global financial system, with most international trade and financial transactions conducted in dollars. At the same time, US military strength has been reinforced by its global alliance system, particularly NATO, and its extensive network of overseas military bases. These factors enable effective power projection, ensure a strategic presence in key regions, and provide influence over critical energy routes, thereby strengthening its role in global politics and the international economic order.

Overall, the conflict has increased regional instability and heightened the risk of further confrontation. By surviving the conflict and imposing costs on US partners, Iran appears to have strengthened its regional position. In contrast, the USA has faced significant challenges in achieving its objectives, while absorbing financial, military, and reputational costs. This suggests a shift from uncontested dominance toward a more complex and uncertain strategic environment.

US dominance is further reinforced by its leadership in scientific and technological innovation, which serves as a key instrument of power in international politics. By maintaining superiority in both fundamental sciences and military technology, the USA secures a strategic advantage over its rivals. Landmark achievements such as the Manhattan Project, the Apollo Program, and the Human Genome Project demonstrate its ability to convert scientific progress into geopolitical influence.

In the contemporary era, leadership in Artificial Intelligence and other emerging technologies has become central to great power competition, shaping the future balance of power. The country’s world-class universities and extensive research funding continue to attract global talent, creating a steady flow of intellectual capital. This fusion of knowledge, technology, and state support enhances both soft and hard power, allowing the USA to maintain a decisive edge in the evolving global order.

Since its independence in 1776, the USA has frequently been engaged in military conflicts in pursuit of its national interests. Its expansion historically involved wars against Native Americans, attempts to invade Canada, conflict with Mexico, the Spanish-American War, and the annexation of Hawaii. In the post-World War II era, U.S. involvement in conflicts has included the Korean War, the Vietnam War, the Gulf War, the Kosovo War, the War in Afghanistan, the Iraq War, and interventions in Libya and Syria. These interventions reflect the consistent use of military power to pursue strategic objectives.

Despite these interventions, no single state or alliance has been able to effectively challenge or defeat US political and military dominance. This is largely due to its deterrence-based strategy and overwhelming military capabilities. As a result, no major power— including China— has demonstrated the strategic confidence to engage in direct conflict with the US–Israel alliance.

However, recent developments suggest that this hegemonic position may be under strain. US policies under the “Make America Great Again” and “America First” agendas, particularly in relation to Iran, have introduced new strategic challenges. Even an economically weakened Iran retains the capacity to challenge US interests in the Middle East, including the possibility of targeting US bases and threatening Israel, despite advanced defense systems such as THAAD and the Iron Dome.

Reports from official sources indicate that the financial cost of the US-Iran conflict exceeded $11.3 billion within the first six days alone. Although the United States maintained air superiority, it reportedly suffered significant equipment losses, including F15 fighter jets, an AN/TPY-2 radar system, a KC135 refueling aircraft, an E3 AWACS aircraft, C130 transport planes, an A10 aircraft, Black Hawk helicopters, and multiple MQ9 Reaper drones. These losses are estimated to exceed $2.35 billion in value.

Beyond immediate financial damage, the extensive use of missile defense systems such as THAAD and Patriot has raised concerns about resource depletion. These systems’missiles are costly and time-consuming to replace, potentially affecting future military readiness. In the longer term, such losses may reduce the USA’s ability to deter major rivals, including China.

More significantly, the conflict has implications for US credibility and influence in the Middle East. If a relatively weaker state like Iran can challenge advanced US defence systems, it may weaken confidence in US security guarantees and raise concerns among allies, particularly within NATO. This not only represents a strategic setback but also a reputational challenge, calling into question the reliability of the USA as a global security provider.

Efforts at de-escalation, including Pakistan’s diplomatic mediation and the “Islamabad Accord,” have not resulted in a stable or lasting peace. The situation remains fluid and uncertain. Any further escalation— particularly additional military action by the USA— could intensify tensions, with Iran likely to respond by targeting US interests in the region.

Overall, the conflict has increased regional instability and heightened the risk of further confrontation. By surviving the conflict and imposing costs on US partners, Iran appears to have strengthened its regional position. In contrast, the USA has faced significant challenges in achieving its objectives, while absorbing financial, military, and reputational costs. This suggests a shift from uncontested dominance toward a more complex and uncertain strategic environment.
