U.S. President Donald Trump's statement on Truth Social that he intends to scale back military exercises with South Korea undermines perceptions regarding the strategic alliance between the U.S. and South Korea. This alliance serves as a significant pillar of South Korea's strategy for resilience and coping with the nuclear threat posed by North Korea. This move comes after years of favorable attitude from the U.S. administration toward South Korea, which was defined by Under Secretary of Defense for Policy Elbridge Colby as a "model ally" due to its large defense industry base and substantial defense spending in light of threats from North Korea and China.\
One of the key components in maintaining South Korea’s national resilience is its reliance on the U.S. nuclear deterrence umbrella, as anchored in the 2023 Washington Declaration. In that declaration, the U.S. committed that any nuclear attack by North Korea on South Korea would be met with a swift, decisive, and overwhelming American response, and that the American commitment rests on the "full range of U.S. capabilities," including nuclear ones. This was accompanied by South Korea's renewed commitment to the non-proliferation regime and to refraining from pursuing an independent nuclear arsenal.
Public opinion polls conducted in South Korea in recent years indicate that the South Korean public supports the alliance between South Korea and the U.S. and views the U.S. as a key partner. However, confidence levels that the U.S. would use nuclear weapons to defend South Korea—while high—are significantly lower than the level of overall support for the alliance. Consequently, support for South Korea developing its own independent nuclear capability is also very high. It is not improbable that Trump’s recent statement will lead to a further increase in this support, driven by fears that the American commitment to defending South Korea is wavering.
Trump’s statements also align with the administration’s moves to re-evaluate the deployment of U.S. forces in Europe, as well as a document sent to NATO member states asking them to review their loyalty to the alliance in light of anticipated cuts to U.S. troops and their lack of support for political moves led by Trump, such as the campaign against Iran. These steps, alongside broader questions regarding the U.S. commitment to European security amid the Russia-Ukraine war, raise concerns about the credibility of American security guarantees to its allies. These questions are even sparking discussions in Europe about the need for an independent European nuclear deterrent, led by Britain and France, that would reduce reliance on the traditional role of the U.S. as the provider of Europe's nuclear umbrella.
For Israel, which, like South Korea, serves as a major U.S. ally, these developments should raise doubts about the ability to rely on the Trump administration—despite the close operational and strategic cooperation demonstrated between the two countries. These doubts are also reflected in data from surveys conducted by the Institute for National Security Studies (INSS), showing that nearly 60 percent of the Israeli public believes Trump supports Israel only when it serves his own interests.
