Trump's former defense secretary sees no end in sight for Iran war — to the benefit of America's 'greatest adversary'

What warning did Mark Esper make about the U.S.-Iran war and its effect on America's attention to China?

Esper’s central warning is strategic distraction. He said China is America’s “greatest adversary,” yet Washington remains focused on the Middle East after more than 20 years of attention there. A long Iran conflict could consume political energy, military resources, and policymaker attention that might otherwise address China’s rise.

The example Esper gave is China’s broad buildup. He said Beijing is strengthening its economy, technology, diplomacy, and armed forces. He called it the largest military buildup in history and pointed to China’s influence in electric vehicles, rare earths, solar panels, and critical materials. These advantages can support wider national power.

The war had lasted eight months when Esper spoke, and he saw no end in the foreseeable future. He said it could continue well into 2027 and possibly reach the next administration in 2029. He urged the United States to work with European and Asian allies on military, diplomatic, economic, and technological efforts focused on China.

What does an economic blockade, or “economic strangulation,” of Iran involve?

An economic blockade, or “economic strangulation,” is a pressure strategy aimed at weakening a country’s economy without relying only on battlefield operations. In this case, the United States uses sanctions, economic restrictions, and a blockade to limit Iran’s economic activity. The intended result is enough pressure to bring Tehran back to negotiations.

The article gives several examples. Trump announced intensified sanctions and restrictions under the label “Economic D-Day.” A White House official said the United States controlled the Strait of Hormuz and that Iran’s economy was collapsing. Esper said the policy could have an impact if it were sustained, although it might not actually bring Iran back to the table.

Esper’s main concern is endurance. Economic pressure works gradually, so Washington must maintain it with time, discipline, and patience. He said those qualities are difficult for states to sustain. The current policy therefore could prolong the war rather than quickly resolve it, especially as the conflict remains at an impasse and large-scale military operations may resume.

How long has the war lasted, and how long does Esper think it could continue?

The conflict had already lasted eight months, according to the article. That duration matters because Esper described the war as having reached an impasse rather than moving toward a clear resolution. The fighting and economic pressure were continuing, while Washington and Tehran had not reached a settlement.

Esper’s forecast was unusually long. At the summit, he said the conflict could continue “well into 2027.” He also described a path in which President Trump might fail to reach an agreement, leaving the war to the next U.S. administration in three years, in 2029. He later told CNBC that he saw no end in the foreseeable future.

The immediate reality was a slower conflict. Esper expected the American blockade to continue, with occasional outbursts from either side. The article also reports that U.S. officials were considering renewed large-scale military operations in the coming weeks. These developments suggest continued pressure, uncertainty, and a risk that the conflict could outlast Trump’s current term.

What happens to U.S. strategy when Washington must keep military and political attention focused on a prolonged Middle East conflict?

When a Middle East conflict continues for years, U.S. strategy can become dominated by immediate crisis management. Leaders must monitor military operations, economic pressure, negotiations, and escalation risks. Esper warned that this focus can crowd out preparation for China, which he described as America’s greatest adversary and a long-term competitor across several forms of power.

The article gives a clear contrast. While Washington focuses on Iran, China is building economic, technological, diplomatic, and military capabilities. Esper highlighted Beijing’s strength in electric vehicles, rare earths, solar panels, and critical materials. He also said China had carried out the largest military buildup in history. A prolonged conflict therefore creates an opportunity for China to keep advancing while attention remains elsewhere.

Esper urged a wider response involving European and Asian allies. He said that partnership should cover military alliances as well as diplomacy, economics, and technology. If the Iran war continues into 2027 or 2029, the United States may face greater difficulty balancing immediate Middle East demands with long-term competition against China.

Why is returning the Strait of Hormuz to normal operation such an important part of any possible U.S.-Iran settlement?

The Strait of Hormuz is a central condition in Esper’s proposed settlement because the conflict has disrupted its normal status. He said Trump would need a deal that returns the strait to the status quo. That requirement makes negotiations harder, since the settlement must address both security control and the economic consequences of the conflict.

The article describes the U.S. blockade and a White House claim that America controls the Strait of Hormuz. The same official said Iran’s economy was collapsing. This connects the waterway to the broader pressure campaign: control and disruption affect how the United States applies economic warfare and how Iran experiences the conflict.

Esper did not say a settlement was imminent. He said restoring normal operation would be “really hard,” alongside reaching an agreement better than the JCPOA. Trump therefore would have to decide whether to accept a difficult compromise and how critics would judge it. Without such a deal, the war could continue or pass to the next administration.

What was the JCPOA, and why does Esper describe it as a benchmark for judging a future Iran nuclear deal?

The JCPOA is identified in the article as the agreement reached during former President Barack Obama’s administration. The article does not detail its provisions, but Esper treats it as the existing benchmark for judging a future U.S.-Iran nuclear settlement. His concern is that a new deal must produce terms stronger than those associated with Obama’s agreement.

Esper said Trump would face two difficult conditions at once. Any settlement would need to return the Strait of Hormuz to the status quo and be better than the JCPOA. He described both requirements as hard, especially the nuclear standard. This makes the agreement a political and policy comparison, not simply a technical negotiating detail.

The benchmark could shape whether Trump accepts a compromise. Esper asked whether Trump would make such a deal and live with the consequences, including criticism of its quality. If no agreement meets that standard, the current blockade and conflict could continue, possibly until the next administration in 2029.

How can control of trade, technology, critical materials, and military power help China gain influence over global affairs?

Control of trade, technology, critical materials, and military power can give China several forms of influence at once. Economic strength supports national power, while control over important industries can affect other countries’ choices. Military capability adds pressure, and diplomacy helps Beijing build support for its preferred rules and institutions.

Esper pointed to China’s position in electric vehicles, rare earths, solar panels, and critical materials. He said the Chinese government can consolidate control and direct the economy toward chosen goals. He also described China’s military buildup as the largest in history and said Beijing is expanding its diplomatic power. These tools reinforce one another.

Esper said China wants to dominate the Indo-Pacific region and, in broad terms, the world by 2049. He argued that China has followed this plan for at least 30 years, including since joining the WTO. His response is a coordinated effort with European and Asian allies across military, diplomatic, economic, and technological areas.
