The global security landscape of 2025 and beyond is evolving rapidly, challenging traditional alliance diplomacy in Northeast Asia. As great powers adjust their strategies in a multipolar world, ideological cohesion within alliances is weakening, giving way to interest-driven partnerships that will increasingly shape the international order. 

    This transformation will have profound implications for potential U.S.-North Korea talks, raising critical questions about whether diplomacy will prioritize peace and denuclearization or be dominated by the strategic interests of major Northeast Asian powers. 

    Northeast Asia’s security structure was viewed mainly through the “new Cold War” paradigm. This framework was grounded in strengthening the U.S.-South Korea-Japan alliance, which sought to reinforce collective deterrence against common adversaries by emphasizing value-based superiority, including democratic governance, human rights, and the rule of law. 

    In response, China, Russia, and North Korea increasingly perceived this as a security challenge and began coordinating more closely to counterbalance this pressure. 

    Following the collapse of U.S.-DPRK talks in 2019, North Korea recalibrated its foreign policy by deepening ties with China and Russia, seeking economic and security support to withstand external pressure. In particular, with the outbreak of the Ukraine War in 2022, Pyongyang’s growing military cooperation with Moscow reflects a strategic alignment in the emerging new Cold War, aimed at counterbalancing the U.S. and its allies. 

In June 2024, Pyongyang and Moscow formalized their security ties by signing a mutual defense agreement, pledging military assistance if a third party attacks either side. Following this, North Korea provided weapons and military personnel to support Russia’s war effort, while Moscow responded with economic aid and possibly advanced military technology. This cooperation has bolstered North Korea’s strategic position as South Korea deepened its military collaboration with the U.S. and Japan, reinforcing Pyongyang’s need to secure alternative security and economic backers. 

    Trump’s foreign policy goals are rooted in his Make America Great Again (MAGA) vision, prioritizing U.S. strategic and economic interests over traditional alliance commitments. This approach has gradually reshaped the international order, accelerating the shift toward a multipolar world where other major powers assert more significant influence and pursue their strategic ambitions. 

    To end the ongoing conflict in Ukraine, Trump stated that he would discuss “dividing up certain assets,” including land and power plants, with Putin during their call in March Just as U.S.-Russia power dynamics have largely dictated Ukraine’s peace negotiations, often sidelining Ukraine itself, this trend suggests that future global diplomatic processes will be shaped more by the strategic interests of major powers in a multipolar world than by genuine conflict resolution efforts. 

    During ceasefire negotiations on Ukraine, Putin and Trump emphasized the need to improve U.S.-Russia relations and discussed broader global security issues, including conflict management and nuclear non-proliferation. For Trump, renegotiating treaties like the Strategic Arms Reduction Treaty (START) and the Intermediate Range Nuclear Forces Treaty (INF) can reassert U.S. leadership in deal-making, while for Putin, direct talks with Washington bolster Russia’s global standing by sidelining Europe in global security discussions. 

    If U.S.-Russian arms control negotiations take shape, North Korea’s nuclear issue could become an area of mutual interest. For Moscow, leveraging its influence over Pyongyang to enhance its role in Northeast Asian security, Washington views engagement with Russia and North Korea as a strategy to counterbalance China’s growing regional influence. 

    To maximize its strategic autonomy, North Korea will exploit great-power rivalries in this evolving power dynamic. It will ensure that its partnerships with Russia and China remain advantageous without becoming overly dependent on either power. 

    While the feasibility of U.S.-North Korea negotiations under Trump remains uncertain, he may seek a diplomatic “win” similar to his 2018 Singapore summit with Kim Jong Un. 

    For Washington, a U.S.-Russia rapprochement could either enhance or undermine its leverage over North Korea, depending on whether Trump accommodates Russia’s role in diplomacy or insists on direct bilateral engagement with Pyongyang. 

    The key policy challenge for the United States is to ensure that Russian involvement does not marginalize Washington’s strategic priorities on the Korean Peninsula. Moreover, if Trump views diplomatic engagement with Pyongyang as a means to counterbalance Beijing’s regional influence, this could serve as an additional incentive for renewed U.S.-North Korea negotiations.  

    For North Korea, engaging the United States remains a strategic maneuver rather than a shift in policy goals. Pyongyang may explore diplomatic outreach to Washington to balance its reliance on Beijing and Moscow and maximize its strategic flexibility in an evolving global order. 

    However, given the persistent lack of trust, Pyongyang will likely maintain close coordination with Beijing and Moscow throughout potential negotiations. It will leverage their support to strengthen its position against Washington while ensuring that its nuclear deterrent remains the regime’s ultimate security guarantee. 

    Ultimately, U.S.-North Korea relations will be shaped less by traditional diplomacy and more by Northeast Asia’s evolving balance of power. While diplomatic engagement may continue, it will function more as a strategic recalibration within great-power competition rather than a genuine pathway to resolving the Korean Peninsula’s long-standing security challenges. 

    While complete denuclearization remains unrealistic, Washington should pursue a phased diplomatic approach, offering targeted economic and security incentives in exchange for verifiable commitments. This strategy would discourage Pyongyang from increasing its reliance on Moscow and Beijing.
