The United States’ diplomatic approach at the United Nations has undergone significant changes, as exemplified by the actions of Dorothy Shea, the highest-ranking U.S. representative at the UN. Two years ago, she described Russia’s invasion of Ukraine as “unprovoked” and “unjustified,” urging member states to condemn Moscow’s aggression and call for an end to the war. However, in February, Shea articulated the Trump administration’s decision to diverge from European allies by not supporting a UN resolution that blamed Russia for its actions on the third anniversary of the conflict.
Despite the typical continuity of diplomatic roles across U.S. presidential administrations, Shea’s interim position highlights the stark shift in U.S. foreign policy under President Donald Trump’s “America First” strategy, which has challenged the post-World War II international order. Shea’s tenure is expected to be longer than planned following Trump’s decision to withdraw his nominee for UN ambassador, Rep. Elise Stefanik, due to the need to maintain a slim Republican majority in the House.
The U.S. position in UN voting has shifted as well. On February 24, the United States joined Russia in opposing a European-supported Ukrainian resolution that demanded an immediate withdrawal of Russian forces. Instead, a competing U.S. resolution expressed regret over the “tragic loss of life” and urged a “swift end to the conflict,” while avoiding direct reference to Russian aggression.
Shea emphasized the need for unity and agreement on fundamental principles, advocating a bold vision of peace. This shift represented a significant change for the U.S. in the 193-member UN General Assembly, where resolutions, though non-binding, reflect global sentiment. Concerns have arisen among allies about how a second Trump term could impact transatlantic relationships and the U.S.’s role in countering aggressors like Russia.
With over 30 years of diplomatic experience under both Republican and Democratic administrations, Shea has consistently executed U.S. policies, regardless of their alignment with traditional positions. Her diplomatic career includes postings in South Africa during Nelson Mandela’s presidency and involvement in the Israeli-Palestinian peace process.
Shea’s early experiences, including hosting Japanese exchange students and her family’s active participation in international relations, spurred her interest in global affairs. After graduating from the University of Virginia, she joined the U.S. Foreign Service and eventually served as Trump’s ambassador to Lebanon, where she gained attention for her criticism of Hezbollah.
While President Joe Biden nominated Shea as the deputy to the UN, the timeline for her replacement remains uncertain. Stefanik’s nomination was withdrawn because her support was vital for advancing Trump’s agenda in the House. Shea continues to lead during a crucial period for U.S. foreign policy, managing changes in international relations and defending significant reductions in foreign assistance.
The administration’s recent proposal to slash State Department funding, which includes cutting nearly all support for international organizations like the UN, reflects its isolationist stance. This proposal poses challenges to the UN’s mandate and work amid funding uncertainties.
