The return of Donald Trump to the White House signals a new era in American politics, marked by shifts in both domestic and international policy. As allies watch the unfolding changes, many feel uncertain about America’s direction. At the heart of this moment is an opportunity: for Trump’s administration to reinforce the United States’ national security and global influence with strategic, powerful actions. Here’s a closer look at the national security imperatives for this administration and what they mean for America’s role on the world stage.
Reshaping a Republican vision
Over a decade, Trump has redefined the Republican Party, moving it from a platform once championed by figures like John McCain and Mitt Romney to a populist vision embodied by leaders like JD Vance and Josh Hawley. For the Trump administration, securing national interests will mean building on this vision but doing so with caution, mindful of the unique security challenges and financial realities the U.S. faces today. The opportunity is there for Trump to enact policies that fortify American power—but these policies need strategic alignment with global and domestic constraints.
The foundation of deterrence
During the previous administration, the U.S. faced growing challenges to its international commitments, which critics argue stemmed in part from the controversial U.S. withdrawal from Afghanistan. This withdrawal left many allies wary of American resolve, potentially weakening U.S. deterrence. The Trump administration now has a chance to rebuild this confidence and signal to both allies and adversaries that America’s commitments are steadfast.
To strengthen deterrence, this administration could consider bolder actions in Ukraine. The Biden administration’s approach was cautious, prompting frustration over its limited and delayed arms deliveries. The Trump administration, in contrast, might pivot to a more assertive stance, ensuring Ukraine receives ample support to repel Russian forces and disrupt any notions of Western hesitancy. By doing so, the U.S. would send a clear message to other global powers, especially China, which has closely watched how the West handles the Ukraine conflict.
Confronting the China challenge
The drawn-out nature of the Ukraine war provides China with valuable insights into Western strategies, vulnerabilities, and technological capabilities. China, with its ambitions for Taiwan and dominance in the Indo-Pacific, benefits from watching U.S. hesitations in action. For a successful Trump administration, deterring China may mean pursuing a two-fold approach: assertive action against Russian aggression and maintaining a robust, visible presence in the Asia-Pacific.
By reaffirming the U.S.’s commitment to Taiwan and building a coalition with Pacific allies, Trump could reinforce that the U.S. will not tolerate Chinese expansionism. Additionally, these actions could counter China’s growing technological and military advancements, which now present some of the greatest challenges to American security.
Funding America’s security
One of the most pressing issues facing the Trump administration is military funding. Although Congress has increased defense spending in recent years, these efforts may still fall short of what is needed. The current defense allocation stands at around 3% of GDP—a level many security experts argue is inadequate given the intensified geopolitical threats.
The Trump administration could champion increased defense spending, perhaps pushing it to 5% of GDP, as advocated by some members of Congress. This spending boost would support vital programs, including rebuilding the Navy, modernizing nuclear arsenals, and increasing ammunition and air defense reserves. Reinvigorating America’s industrial base and defense capabilities would not only prepare the U.S. for potential conflicts in the Pacific but also act as a powerful deterrent to adversaries.
A strategic step forward in defense policy
Trump’s “America First” approach emphasizes economic nationalism, trade protectionism, and transactional relationships with allies. However, many experts argue that maintaining robust alliances is essential to confronting the challenges posed by adversarial coalitions. With adversaries like China, Russia, North Korea, and Iran forming strategic partnerships, the Trump administration must balance its populist approach with a willingness to foster crucial alliances.
If the Trump administration reaffirms its support for NATO and Pacific partnerships while setting clear expectations, the U.S. can continue to rally global cooperation in a way that enhances its power without compromising its principles.
Addressing the pitfalls
Even with strong deterrence and defense plans, challenges lie ahead. Trump’s foreign policy tendencies may lead to risky decisions, especially when dealing with authoritarian leaders. While some in Trump’s circle advocate for a “madman” theory—using unpredictability as a tool to deter adversaries—this approach risks creating uncertainty among allies, who may feel compelled to seek their security assurances elsewhere.
At the domestic level, if the administration directs military resources toward border enforcement or uses the military for internal policing, it risks alienating the public and disrupting the longstanding relationship between the military and civilian spheres.
A strong, unified future
Despite the potential for polarizing moves, the Trump administration has a unique opportunity to reshape and reinforce American national security in a way that prioritizes both strength and stability. By focusing on deterrence, increasing defense spending, and balancing international partnerships with a decisive U.S.-first approach, the administration can not only secure America’s global standing but also contribute to a more resilient and united nation.
In this pivotal moment, a bold yet strategic approach to national security could be the defining legacy of Trump’s second term, positioning the U.S. to thrive in an increasingly unpredictable world.
