On Wednesday, U.S. Senate Armed Services Committee Chairman Roger Wicker (Republican-Mississippi) stated that maintaining the U.S.-South Korea alliance’s focus on North Korea is the most effective way to counter threats.
Wicker made these remarks during a video address at the Asan Plenum 2026 conference held at the Grand Hyatt Seoul, emphasizing that shifting burdens onto allies contradicts the alliance’s purpose.
Wicker’s comments drew attention as he expressed concern about the Donald Trump administration’s strategy to place more responsibility on South Korea for deterring North Korea as part of modernizing the alliance. He argued that U.S. disengagement from key regional conflicts is not shared responsibility but rather avoiding responsibility.
Wicker stated that he has long recognized the political, strategic, and moral value of America’s alliances. He supports the collective efforts, which it has called burden sharing for decades.
He continued that however, some in Washington view these alliances with contempt, claiming allied nations have become mere dependents. They’re rejecting mutual burden sharing in favor of a new concept called burden shifting.
Wicker asserted that this burden-shifting concept involves the U.S. rapidly transferring its conventional deterrence responsibilities to allies. He strongly disagrees with this approach.
The Trump administration formalized a strategic flexibility policy in its January National Defense Strategy (NDS), aiming to enhance South Korea’s conventional deterrence against North Korea. The NDS also outlined a limited support role for U.S. Forces Korea.
While Wicker is known for emphasizing the importance of countering China, he reportedly holds a critical view of the Trump administration’s alliance modernization plans.
Describing the U.S.-South Korea alliance, Wicker said that it’s characterized by collective responsibility. While it began as a military commitment, it has evolved to encompass cultural ties, robust trade, and cooperation in sectors like shipbuilding, critical minerals, artificial intelligence (AI), and energy.
Though the alliance has matured, he stressed that its core mission of deterring and defending against aggression remains unwavering. The U.S.-South Korea relationship is unique as America’s only comprehensive bilateral military alliance.
Wicker added that it must modernize the alliance to address current threats and capabilities, but these changes shouldn’t diminish the focus on North Korea.
He specifically noted that Kim Jong Un constantly reminds them that North Korea is our primary adversary in the peninsula, with China presenting the next significant challenge. Maintaining the alliance’s focus on North Korea is the best strategy for addressing both threats, and the U.S. will continue to play its part.
In conclusion, Wicker affirmed that it will maintain credible extended deterrence for South Korea and other treaty allies, employing all means including conventional forces, missile defense, and the nuclear capabilities.
