Forging a National Security Agenda: An Open Letter to the President-Elect

At noon on January 20, 2025, you will place your left hand on the Bible, raise your right hand, and “solemnly swear to preserve, protect and defend the Constitution of the United States.” The Constitution sets out, clearly and unambiguously, the priorities on which you must focus: “establish justice, ensure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty to ourselves and our posterity”—IN THAT ORDER.

The Constitution vests the President with the dual role of chief executive—atop one of three “separate and coequal” branches of government—and commander in chief. Understand the institutions that will serve you, or they will hinder your progress through bureaucratic inertia. Learn all you can about the military—its capabilities, its role in the national security architecture, and, most importantly, its values and ethos. Earn the trust of our service members, not merely their obedience. Perhaps more than any other organization comprising the mechanisms through which you govern, the military needs your respect and a finely-honed grasp for what it can and cannot achieve.

Unleashing the dogs of war is truly an act of kings. Remember that it is Congress who declares war and commits the nation to a fight. Seek their advice and consent, or they’ll stymie you at every step.

 Do not commit military force unless you are fully committed to winning. You owe it to those who would sacrifice life and limb—and their families—to ensure the cause is just, the mission achievable, and the resources sufficient to the task at hand. Make sure the American people fully understand the nature of the fight and the value of the objectives—in both magnitude and duration. Without candor on all scores, political support will evaporate when you need it the most.

It’s impossible to win unless you state clearly what is at stake. Sun Tzu’s admonition to “know the enemy and know yourself” is as resonant today as it was when first written five millennia ago. Never equivocate when it comes to declarations of hostile intent. Mein Kampf and The Communist Manifesto were both initially dismissed as delusional ravings. The ensuing cost was millions of lives, two continents in ruins, and repercussions still felt around the world.

Strategic endeavors are notoriously difficult to end advantageously. Always consider your desired end-state before taking the first step. Realize that indecision and inconsistency are debilitating and dangerous. There are no “time outs.” Your vacillation will not freeze world events. In a competitive environment, any vacuum will be filled—often by malign actors —leaving every subsequent action fraught with even greater risk. Never assume others are naïve, or willing to subordinate their interests to yours.

Beware of hubris. Humility is, indeed, a virtue, particularly in a volatile, inherently unpredictable environment. The “global balance of power” is a literal construct—it’s truly about equilibrium. The only questions are who will lead and how the balance will be restored.

Global peace and prosperity are inextricably intertwined. Both are anchored in America’s strength and resolve.

As a global power with global commitments, standing by our allies is the gold standard of credibility—a norm by which you will be judged. While you should think long and hard before taking on new responsibilities, existing obligations must be honored. Therefore, the military you command must be able to deter aggression, defend allies, and defeat opponents across the full range of operations, in all domains—and it must be perceived as such. Deterrence is in the eye of the beholder; it’s measured in the breach. Trust and credibility cannot be surged on demand—both take a long time to build but can be shattered in a moment of inattention.

National security strategy requires a constant adaptation of ends, ways, and means to shifting conditions, in an environment where chance, uncertainty, fog, and friction dominate. To add to the complexity, strategy is both multi-sided and multi-dimensional: The objectives, intentions, actions, and reactions of allies and opponents are often opaque and variable. Policy goals (ends) play a critical role, as do diplomatic, financial, technological, and military resources (means). Other factors— history, geography, culture, ideology, ethos, personalities —influence behavior in subtle, but important ways. Grasping their interplay is the essence of statecraft.

Three elements underpin strategic leadership: grasp of strategic practice; a knack for innovation; and the ability to align domestic and international concerns.

Strategic practice is the crux of the president’s job. Strategy guides action. Its focus is on how to use available means to achieve the desired ends with acceptable risk—avoiding single-issue fixation, while balancing current requirements with future imperatives.

Innovation is the ability to think anew and develop creative approaches to changing circumstances. Innovation stems from foresight—the aptitude to read current and emerging trends while anticipating their future direction. It requires courage and perseverance, as well as the readiness to “break glass,” especially in entrenched bureaucracies.

Do not shy away from discarding assumptions that—while comfortable or comforting—fail to account for new strategic realities. Think holistically: capture both the whole and its component parts; grasp multi-dimensional, dynamic relationships as they are today and as they might evolve tomorrow; strive to relate seemingly disparate activities to one another; anticipate second- and third-order effects of both actions and inactions. The alternatives to strategic thinking are incoherence, confusion and the disappointments that are sure to follow false expectations.

The President of the United States stands at the crucial intersection of forging grand national and international interests into executable objectives that yield desired outcomes when translated into feasible, acceptable, and suitable courses of action. Lofty aspirations and good intentions must be anchored in fiscal and operational realities, or else be seen as empty gestures that create a dangerous gap between words and deeds.

Surround yourself with men and women of character. Seek a diversity of viewpoints and think of diversity as encompassing far more than gender or ethnicity. Cherish those who speak truth to power, unbound by self-interest and political correctness. These virtues are both rare and fragile. You’re doomed to fail if you don’t deliberately foster and protect the people who possess such attributes.

Recognize the difference between facts and opinions. Always ask your advisors how they know what they view as facts. Encourage people to identify pitfalls along the path and offer alternative solutions. But once you make a choice, the decision is yours to own, and the buck truly stops with you.

The challenges are daunting and threats abound at home and abroad. Forces of evil have been allowed to flourish. America’s credibility and stature are in dire need of renewal. Lead with commitment and consistency: Don’t “pivot” and don’t obfuscate. People of good will everywhere will follow if you chart a clear path and compellingly articulate the vital interests that are at stake.

The world is literally on fire, and more dramatic upheavals are surely on the way. We have slayed the Communist dragon. In its stead, we face vipers’ nests of unpredictable perils.

As the conflagration in the Middle East clearly demonstrates, the global war against violent Islamism is far from over. Who will prevail and what kind of world will emerge in the aftermath remain open questions. The next president must make a serious effort to win this war in a manner that establishes a better peace and secures U.S. strategic interests. Start by understanding the nature of the threat and follow through with a compelling, fact-based strategy, articulating the kind of war we are in, what “winning” actually looks like, and what is necessary for victory.

Concurrently, the likelihood of war with peer competitors has grown to a level unseen since 1939. Global stability and security are threatened by a new Axis: resurgent Russia, rising China, malign Iran, and erratic North Korea. All either already possess or are close to acquiring nuclear, space, and cyberwarfare capabilities.

Further proliferation of weapons of mass destruction represents a clear and present danger. The U.S. military can no longer rely on its technological edge or the advantages of unchallenged global reach and global power. Every domain—land, sea, air, space, and cyberspace—is a contested environment. Emerging technologies make it easier for adversaries to deny access and target America’s core strengths, including the homeland. Consequently, as the wars in Ukraine and the Middle East vividly demonstrate, future conflicts will be costly, violent, and difficult to control. The potential for strategic surprise is high, and our military’s strength and residual capacity are at a historic low.

Beware of complacency and strategic myopia. History is replete with examples of disasters born of lack of foresight. The lessons of history are clear: Aggressors tend to assume risks that seem irrational and, thus, improbable to the intended victim. This leads to strategic surprise followed by a belated, often chaotic response, and the potential for catastrophic failure. Do not trivialize adversaries’ stated intent merely because their aspirations appear far-fetched, or their capabilities seem inferior. With the increasingly rapid diffusion of military technology, these facts can change overnight.

America is precariously close to the abyss. The national debt is staggering—$35.81 trillion and growing by the minute. Mind the gap between ends and means! If you permit reality to outpace strategy and budgets, you will always be reactive and, therefore, unable to bring power to bear in time to achieve the desired objectives. Worse, strategic incoherence undermines America’s credibility, stifles innovation, and diverts attention from true exigencies.

You are taking the helm during a perfect storm fueled by the most toxic political atmosphere in recent memory—amid an extraordinary meltdown in respect for authority, truth, law, and order. The social compact that makes the United States whole—as well as the rules-based global order—are both fraying at the seams. You must commit to restore the moral compass that has guided America since its inception.

I leave you with Abraham Lincoln’s words: “It is for us the living … to be dedicated to the great task remaining before us … that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth.”
