In February 2023, during an unexpected visit to Kyiv, US President Joe Biden demonstrated his support for Ukrainian President Volodymyr Zelensky amidst blaring air sirens. Reflecting on that day, Biden expressed a deep sense of America’s global significance. As the upcoming presidential election looms, the world is keenly observing who will assume leadership of this influential nation. Will Kamala Harris continue Biden’s approach, emphasizing that America must remain engaged in these turbulent times? Or will Donald Trump return to power, advocating for “Americanism” over “globalism”?

The current geopolitical landscape raises questions about the United States' role in global affairs. Autocratic regimes are forging their own alliances, and conflicts in places like Gaza and Ukraine challenge the effectiveness of US influence. Despite this scrutiny, America’s substantial economic and military capabilities continue to play a crucial role in international alliances. Observers are now weighing the implications of this critical election on global stability.

Rose Gottemoeller, former deputy secretary general of NATO, warns that Trump’s presidency could be detrimental for Europe, recalling his past threats to withdraw from NATO. The US accounts for two-thirds of NATO’s military expenditures, and its defense budget surpasses that of the next ten nations combined. Trump asserts he pressures other NATO members to meet their defense spending commitments—only a fraction currently do.

If Harris wins, Gottemoeller believes NATO will be in capable hands but cautions that she will maintain pressure on Europe regarding military spending. However, should Republicans gain control of Congress, there might be less enthusiasm for foreign military engagements. This could lead to increased pressure on Ukraine to negotiate an end to the conflict amid dwindling bipartisan support for aid packages.

Regardless of the election outcome, Gottemoeller remains confident NATO will endure, although she emphasizes that Europe must take a leadership role. The next president will face significant global challenges reminiscent of Cold War tensions.

Comfort Ero from the International Crisis Group underscores America’s pivotal position in international peace efforts but notes its diminished capacity to mediate conflicts effectively. The complexity of modern warfare has escalated as regional powers engage in conflicts with competing interests.

Ero criticizes the inconsistency in how the US addresses international conflicts and emphasizes that both potential candidates have important foreign policy challenges ahead. Harris maintains support for Ukraine while calling for an end to civilian suffering in Gaza. Trump claims he can bring peace to the Middle East but faces skepticism due to his past actions and rhetoric.

The upcoming election holds profound implications not only for American citizens but also for global dynamics related to climate change and international relations. Leaders like Mary Robinson advocate for principled leadership from the US as it grapples with pressing global issues. The world awaits the decision that could reshape its future trajectory significantly.
