In Washington’s strategy debate over two fronts at once, the Iran war is emerging as a direct test of the U.S. ability to sustain focus on Asia, where U.S. officials and allies worry China’s moves toward Taiwan could accelerate when American resources are stretched. The Associated Press reported that, as the United States targets Iran’s nuclear and missile programs, military assets and attention previously allocated to the Asia-Pacific have been shifted away. That shift is arriving as Trump seeks to meet with Xi next month, with critics warning that the timing could change Beijing’s calculations about when to act.
AP reported that the Iran war also helped drive a delay by several weeks in Trump’s highly anticipated trip to China. Skeptics of U.S. involvement in the Middle East framed that schedule change as another sign that Washington is getting distracted at the cost of strategic interests in Asia, where Beijing seeks to unseat the U.S. as the regional leader.
Danny Russel, a distinguished fellow at the Asia Society Policy Institute, argued the concern is not just about logistics but about strategic timing. He said: “This is precisely the wrong time for the United States to turn away and be sucked into another intractable Middle East conflict,” and added that while “Rebalancing to Asia is highly relevant to America’s national interests,” it has been undercut by what he described as “many bad decisions.”
On the other side of the argument, some officials defending Trump’s approach say the forceful steps being taken in Iran and other places are part of a broader competition with China. Matt Pottinger, who served as a deputy national security adviser in the first Trump administration, said in a recent podcast that “Beijing is the chief sponsor for the adversaries that President Trump is dealing with sequentially,” and argued that it is “wise to do this sequentially.”
The way the conflict could widen beyond one region also came up in remarks by NATO’s secretary general. Mark Rutte told an audience in Washington that conflict “may not be confined to a single theater,” suggesting China could use “junior partners” elsewhere to divert U.S. attention if it moved against Taiwan. Rutte said: “Most likely it will not be limited, something in the Indo-Pacific to the Indo-Pacific,” and added, “It will be a multi-theater issue.”
Senator Jeanne Shaheen, the top Democrat on the Senate Foreign Relations Committee, recently led a bipartisan group of senators to Taiwan, Japan and South Korea to hear concerns about how the Iran war is affecting energy costs and the departure of U.S. military assets, including missile defense systems from South Korea and a rapid-response Marine unit from Japan. After returning, Shaheen sought to reassure the group and told AP that the stakes for Asia are closely connected to deterrence: “Failure is not an option,” she said. “We know China has already said they intend to take Taiwan by force if they need to, and they’re on an expedited time schedule. And we also know that what happened in Europe, in the war in Ukraine, in the Middle East is affecting those calculations.”
AP also reported that former Biden administration deputy secretary of state Kurt Campbell said he is worried that capabilities the U.S. accumulated in the Indo-Pacific might not return in full even after the Iran war ends. Zack Cooper, a senior fellow at the American Enterprise Institute who studies U.S. strategy in Asia, said the longer the Iran conflict lasts, the more it will pull resources and focus away from Asia, and he warned that future arms sales to the region could be affected. Cooper also pointed to how preparations in China’s economy could contribute to leverage during a prolonged conflict.
The broader context dates back to Barack Obama’s “pivot” to Asia, first articulated in 2011 as the U.S. sought to leave behind the wars in Iraq and Afghanistan. AP said that even after that strategic rebalance, the effort faced setbacks, including the failure of a proposed trade agreement, the Trans-Pacific Partnership, to get through the U.S. Senate. It also said that after Trump took office in 2017, he withdrew from the partnership and launched a tariff war with China, while Biden kept Trump’s tariffs and tightened export controls on advanced technology even as he strengthened regional alliances.
By late 2025, AP reported that Trump rolled out a national security strategy that narrowed the U.S. approach in Asia to military deterrence in the Taiwan Strait and the First Island Chain, described as a string of U.S.-aligned islands off China’s coast. AP said the document also identified economic interest in securing access to advanced chips sourced largely from Taiwan and protecting shipping lanes in the South China Sea, while directing that attention to the Middle East should be reduced as American energy production ramps up. Then came the Iran war, and with it, the renewed concern that the United States may again be pulling military assets and strategic attention away from Asia at a moment critics and lawmakers see as time-sensitive for Taiwan.
