The United States is one of the United Nations’ most important stakeholders. The UN was created at the initiative of the US after World War II. Washington provides the largest financial contribution to the UN’s overall budget. The US hosts the UN’s headquarters in New York. The UN Security Council sits at the apex of a 75-year old Rules Based International Order (RBIO) heavily devised, underwritten and anchored by the United States.

Consecutive US administrations up to 2016 broadly supported the post-1945 multilateral architecture and RBIO, which they saw as advancing US power and geostrategic interests.1 The Trump Administration has broken away from this previous Beltway consensus. Since 2017, US foreign policy has become more transactional, mercantile, nationalist, and unpredictable, with a greater emphasis on sovereignty and a reduced focus on alliances. The Trump Administration, unlike its predecessors, has often seen the RBIO as constraining, rather than advancing, US national interests. It holds a global outlook that is more Hobbesian: a power-based international system with competition between states. The President has described this approach to the UN General Assembly as ‘Principled Realism’.2

An important question for other UN Member States is whether this shift in US global outlook under the Trump Administration marks a four year aberration from – or the new normal for – US foreign policy. The outcome of the 2020 Presidential election will be fundamental in determining this.

However, US foreign and multilateral policy is also changing in response to longer term domestic and geopolitical shifts. Internationally, the rise of new Great Powers and new global threats (such as climate change and artificial intelligence) have placed stresses on the post-1945 international system.3 Domestically, there is growing weariness amongst much of the US public regarding the global role of the US, and a feeling that the current international system does not always deliver for US interests. The Trump Administration has accelerated, but did not create, this dynamic.

Notes

1 There have been instances where previous US administrations have acted in a way that was not seen by others as fully consistent with support for a RBIO. For example, the Iraq War of 2003 marked a rupture between the UN and the US. However, the foreign policy of each US administration from 1945 to 2016 was to broadly support the post-1945 multilateral architecture.

So, when we make a decision, at the will of the American ppl, abt where to locate OUR embassy, we don’t expect those we’ve helped to target us. On Thurs there’ll be a vote criticizing our choice. The US will be taking names.” Foreign Policy magazine quoted an email from Ambassador Haley to other UN Ambassadors regarding the upcoming UN vote: “As you consider your vote, I want you to know that the President and U.S. take this vote personally ... The President will be watching this vote carefully and has requested I report back on those countries who voted against us. We will take note of each and every vote on this issue.” in Colum Lynch, “Haley Warns Diplomats on Jerusalem: Trump Is Watching You”, Foreign Policy, 19 December 2017, https://foreignpolicy.com/2017/12/19/haley-warns-diplomats-on-jerusalem-trump-is-watching-you/
