🧵 In the forthcoming issue of @ForeignAffairs, I argue that the time has come to build a collective defense alliance in Asia—the Pacific Defense Pact—initially comprising Australia, Japan, the Philippines, and the United States.

American policymakers have “too often failed to press on China’s pain points or even develop options for doing so.” Read @elyratner and Nick Danby on why Washington must “be ready to go on offense.” foreignaffairs.com/china/fau…

“China’s success in cornering the Trump administration was not simply a result of the United States’ failure to secure its supply chains,” write @elyratner and Nick Danby. “It reflected a profound failure of U.S. strategy.” foreignaffairs.com/china/fau…

China “has been a clever practitioner of finding the gaps and seams in American power,” write @elyratner and Nick Danby. By contrast, American policymakers have “too often failed to press on China’s pain points or even develop options for doing so. foreignaffairs.com/china/fau…

Important piece in @ForeignAffairs by the Biden admin’s top Pentagon Asia official @elyratner
Replying to @elyratner
China's ambitions to dominate the region remain unchanged, and its military capabilities are growing. A Beijing-led order in the Indo-Pacific would relegate the United States to the status of a diminished power, making us less prosperous and secure.

Looking forward to this great discussion tomorrow.
The Indo-Pacific is now, more than ever, a vital theater of competition—one in which U.S. allies could play a decisive role in deterring regional adversaries. @elyratner, @DavidFeith, @AmbVMKwatra, and @LisaCurtisDC will join @AsiaLens at the CNAS 2026 National Security Conference for a panel on burden sharing and cooperation in the region.

NEW in the July/August issue of @ForeignAffairs: For decades, U.S. strategy has failed to build competitive leverage over China. Nick Danby and I lay out how to change that, from chips and trade to the dollar and energy. foreignaffairs.com/china/fau…

On Hegseth’s soft-pedaling of China, in @nytimes: “Trump’s accommodation of China may yield more military engagement in the near term, but it will also invite greater PLA coercion against U.S. allies. That’s not a recipe for strategic stability.” nytimes.com/2026/05/30/world…

My contribution: — China is a lower priority in Trump’s 2nd term; views inside more mixed. — “All of this comes together to create this softer policy we see now, philosophically this group appears geared toward a more accommodationist approach to China.”politi.co/3PkLxkQ

Spoke with @NewsHour on Trump’s visit to China, including how Taiwan and the war with Iran are shaping the summit.
President Trump is in Beijing for a state visit to America’s chief global competitor, and increasingly, its chief geopolitical rival. Trump has long targeted China as an economic foe of the U.S. while cultivating a relationship with President Xi Jinping. @nickschifrin reports.

The Trump administration is pursuing a policy of accommodation toward China that will leave the U.S. with “less leverage, fewer partners and wider gaps to close.” My latest in @FT: ft.com/content/1445c85a-7b3e…

Thank you @elyratner for the vote of confidence in #Taiwan. We’ll do all we can to acquire the right arms & transform our military for effective deterrence. Still more to be done. Timely passage of the special budget by the LY is crucial.

Washington can't let this period of geopolitical flux put cross-Strait deterrence at risk. In a new piece for @NikkeiAsia, my former Pentagon colleague Lauren Dickey and I lay out concrete steps Congress can take to help strengthen Taiwan's self-defense capabilities.
