US Commander Says Indo-Pacific Exercises Geared Toward Deterring Taiwan Invasion

The U.S. Army’s top commander in the Indo-Pacific has said that the timing of one of the U.S. military’s largest regional exercise series is based on periods when Beijing would be most likely to launch an amphibious invasion of Taiwan, offering one of Washington’s clearest indications yet that its regional military planning is focused on deterring a cross-strait conflict.The remarks on June 23, made by Gen. Ronald Clark, commander of U.S. Army Pacific, also underscore an expanding role for U.S. forces stationed in South Korea and highlight how allies across the first island chain are becoming increasingly integrated into contingency planning for a potential Taiwan crisis.Speaking at the Association of the U.S. Army’s Coffee Series event, Clark said that the annual Operation Pathways exercise comprises 53 linked military exercises conducted in two phases—May through June and September through October.He said those periods were selected because sea conditions are generally most favorable for the Chinese Communist Party (CCP) to launch an amphibious assault on Taiwan.Clark emphasized that maintaining credible combat power across the Indo-Pacific remains essential to deterring conflict before it begins.He also stressed the importance of strengthening relationships with allies and partners while expanding the U.S. Army’s forward presence throughout the region.“Understanding the terrain and the requirements needed to maintain strength forward has led to placing prepositioned stocks on the ground in South Korea, Japan, the Philippines, and Australia,” Clark said.Army prepositioned stocks consist of heavy military equipment—including armored vehicles, ammunition, and other supplies—stored overseas so troops deployed from the United States can rapidly draw equipment and enter combat if a crisis erupts.Exercises Reflect Operational PreparationYu Tsung-chi, former dean at Taiwan’s National Defense University, told The Epoch Times the exercises represent far more than routine military training.“The entire series of U.S. military exercises is aimed at preventing the CCP from using military force against Taiwan,” Yu said.He said the program combines realistic operational training with forward deployment measures, including pre-positioned ammunition, fuel reserves, and force deployments.“These actions send a clear signal,” Yu said. “The United States is linking democratic partners across the first island chain to prepare for coordinated military deterrence against the CCP.”Su Tzu-yun, a researcher at Taiwan’s Institute for National Defense and Security Research, told The Epoch Times that Clark’s unusually direct explanation of the exercise’s purpose carries several strategic messages.First, he pointed to Clark’s references to U.S. forces based in South Korea, as security on the Korean Peninsula and stability in the Taiwan Strait are increasingly interconnected.Given South Korea’s geographic proximity to China, any major regional conflict would inevitably affect both South Korean and U.S. forces stationed there, making coordinated planning a practical military necessity.Second, Su said Clark’s public messaging is intended to strengthen deterrence by making Beijing aware of the potential costs of military action.He compared Operation Pathways to recent U.S.–Japan exercises such as Resolute Dragon and Keen Sword, which similarly demonstrate allied readiness without explicitly signaling imminent conflict.U.S. soldiers from the 2nd Infantry Division and South Korean soldiers participate in a river crossing exercise as part of the Ulchi Freedom Shield exercise in Yeoju-gun, South Korea, on August 27, 2025.
