The Pentagon’s Battle for the Future Is Missing the Most Important Question: What Kind of Security Do Americans Need?
As Pentagon leadership struggles over military modernization, political ideology, and weapons procurement, the American public is being left out of a debate that will shape national priorities for decades.
The Pentagon is fighting over the future of the United States Army. But while military leaders, political appointees, and defense contractors compete to determine what the next generation of American warfare will look like, a far more fundamental question remains unanswered: Why does the United States continue to define national security primarily through its capacity to wage war?
That question is conspicuously absent from the Association of the United States Army’s (AUSA) Annual Meeting and Exposition, taking place October 12–14 in Washington, D.C. The gathering brings together military officials, international delegations, and weapons manufacturers for three days of discussions about military technology, procurement, and strategic priorities.
According to AUSA, the event features more than 750 exhibits and draws representatives from approximately 100 countries. It is an enormous marketplace for the technologies and industries that sustain modern warfare.
Yet behind the polished exhibitions of autonomous vehicles, drones, advanced artillery, and artificial intelligence lies an increasingly fractured Pentagon leadership.
A recent POLITICO report by Jack Detsch describes a struggle between Defense Secretary Pete Hegseth’s political allies and military modernization advocates associated with former Army Secretary Dan Driscoll.
The dispute is revealing—not simply because it exposes divisions within the Pentagon, but because both sides remain committed to expanding America’s capacity for military dominance.
One faction wants to transform warfare through advanced technologies. Another emphasizes ideological conformity and traditional military discipline.
Neither appears particularly interested in transforming the country’s understanding of peace.
A Pentagon Divided Against Itself
According to POLITICO’s October 12 reporting, Hegseth’s leadership has disrupted the Army’s internal hierarchy, unsettling military officials and creating uncertainty among defense contractors and American allies.
The reported tensions pit advocates of technological modernization against officials more closely aligned with Hegseth’s political and cultural agenda.
The Pentagon disputes that any such internal battle exists, maintaining that its senior leadership is unified around modernization.
Nevertheless, the questions surrounding the Army’s future extend beyond personnel disagreements.
The modernization proposals described in the report include the acquisition of vast numbers of drones, the development of new logistics systems, and deeper partnerships with Silicon Valley technology companies.
These initiatives are being discussed against a backdrop of rapidly evolving autonomous weapons systems and the growing use of artificial intelligence in military operations.
Such technologies raise profound ethical questions.
Who is accountable when an autonomous system makes a lethal mistake? How much human judgment should be removed from decisions involving life and death? What happens when increasingly inexpensive weapons systems make military confrontation easier to initiate?
And perhaps most importantly, does the acceleration of military technology actually make the world safer?
These are not abstract philosophical concerns. They are questions that should shape congressional oversight, international agreements, and public debate.
Yet the pressure to innovate militarily often moves faster than democratic institutions can evaluate the consequences.
The Military-Industrial Complex Is Thriving
While Pentagon officials struggle over strategic direction, the defense industry continues to position itself for enormous commercial opportunities.
At AUSA, major weapons manufacturers—including Lockheed Martin and Boeing—share space with emerging military technology firms and international suppliers.
The exhibition includes artillery systems, counter-drone technologies, autonomous ground vehicles, and advanced missile defenses.
South Korea’s Hanwha Defense is showcasing its K9 howitzer, while Israel Aerospace Industries is introducing an artificial intelligence-enabled counter-drone system.
European governments are also seeking arrangements with American manufacturers to expand weapons production and address military supply shortages.
The gathering illustrates the extraordinary international reach of the arms industry.
It also reveals a structural problem in American defense policymaking: The organizations that profit from military expansion are deeply embedded in conversations about what national security should require.
This does not mean every new military system is unnecessary or that every defense contractor acts improperly. Governments have legitimate responsibilities to protect their populations.
But a procurement system that consistently rewards the development and acquisition of more sophisticated weapons creates powerful incentives to prioritize military solutions over diplomatic alternatives.
Weapons production generates contracts, political influence, jobs, and corporate revenue. Preventing a war through negotiation rarely produces comparable commercial rewards.
That imbalance deserves far greater scrutiny.
President Dwight D. Eisenhower warned Americans about the dangers of the military-industrial complex in his 1961 farewell address.
More than six decades later, his warning remains remarkably relevant.
The danger is not merely that weapons manufacturers influence policy. It is that military spending becomes so deeply woven into political and economic institutions that questioning its scale begins to seem unrealistic.
The Opportunity Cost of Endless Militarization
Every national budget reflects a set of moral and political choices.
Money committed to military procurement is money that cannot simultaneously be invested in affordable housing, public education, health care, environmental protection, or other civilian priorities.
These tradeoffs are particularly significant when weapons acquisitions become multiyear commitments that shape federal spending far into the future.
Supporters of military expansion argue that new threats require new technologies and increased preparedness. Those threats cannot simply be dismissed. Russia’s war against Ukraine, regional conflicts, and the proliferation of increasingly destructive weapons present genuine security challenges.
But recognizing those challenges does not mean accepting military expansion as the only responsible response.
National resilience also depends upon healthy communities, functioning infrastructure, economic opportunity, trusted institutions, and an educated population.
A country cannot purchase lasting security through weapons systems alone.
For communities facing inadequate schools, rising housing costs, inaccessible medical care, and persistent poverty, the definition of national security often looks very different from the one presented inside a defense industry convention hall.
A family unable to afford medical treatment is experiencing insecurity.
A child attending an underfunded school faces diminished opportunity.
A community struggling with contaminated drinking water confronts a threat to public well-being.
These circumstances may not appear in military threat assessments, but they affect the strength and stability of the nation.
A more comprehensive approach to security would acknowledge that protecting people requires much more than preparing for armed conflict.
America’s Allies Are Being Drawn Deeper Into the Arms Economy
The Pentagon’s internal disagreements have consequences beyond the United States.
According to POLITICO, European governments attending AUSA are particularly interested in air defense, counter-drone capabilities, and cooperative weapons production.
Some are concerned about possible delays in American weapons deliveries because of stockpile shortages associated with the Iran war.
Their concerns underscore the consequences of a global security system heavily dependent upon American military production.
As nations respond to real or perceived threats by expanding weapons inventories, their competitors may interpret those acquisitions as reasons to increase their own military capabilities.
The result can be a cycle of escalating armament, even when the stated intention of each participant is defense.
History demonstrates that arms races can intensify distrust, heighten tensions, and divert resources away from human development.
The appropriate response is not to deny countries their legitimate security concerns. It is to recognize that sustainable security also requires diplomacy, arms control, conflict prevention, and reliable international institutions.
Military preparedness without meaningful diplomatic engagement risks becoming a permanent condition rather than a temporary necessity.
And when the political and economic rewards of weapons production become entrenched, peace itself can begin to look like a disruption to established interests.
Political Loyalty Cannot Replace Strategic Accountability
The reported struggle within the Pentagon also raises concerns about civilian oversight, professional military judgment, and the politicization of national defense.
Civilian control of the military is a fundamental principle of American democracy. Elected leaders and their appointed officials have the authority to establish defense priorities.
But responsible civilian leadership also requires an environment in which military professionals can present evidence, challenge assumptions, and identify operational risks without fear of political retaliation.
When officials become reluctant to question decisions or discuss institutional problems openly, accountability suffers.
Likewise, the use of cultural and ideological disputes to define military leadership priorities risks distracting the public from more consequential questions about strategy, spending, and international stability.
The central issue should not be whether military leaders conform to a particular political identity.
It should be whether national defense policies are effective, lawful, transparent, and consistent with the country’s democratic obligations.
Congress has an indispensable role in answering those questions.
Lawmakers should scrutinize weapons procurement decisions, demand clear justification for military expenditures, evaluate the humanitarian implications of emerging technologies, and ensure that the public has meaningful access to information about national defense priorities.
A military accountable only to its internal hierarchy and political leadership is not enough.
In a democracy, national security must remain accountable to the people whose resources and lives are placed at risk.
What Would a Peace Economy Look Like?
The Peace Economy Project has long argued that the United States must reconsider how it allocates resources between military power and human well-being.
A peace economy does not require ignoring international threats or pretending that armed conflict can disappear overnight.
It requires treating diplomacy, economic justice, public health, education, environmental sustainability, and international cooperation as essential components of national security.
That means asking different questions when national leaders discuss the future.
Instead of asking only how many drones the Army should purchase, policymakers should also ask how investment in conflict prevention might reduce the need to deploy those drones.
Instead of evaluating technological innovation solely by its military applications, the government should consider how publicly supported research can strengthen civilian infrastructure and improve human lives.
Instead of measuring international influence primarily through weapons sales and military partnerships, the United States should examine its capacity to foster cooperation, support development, and help resolve conflicts before they become wars.
This approach would also require greater transparency regarding defense contractors and their influence on procurement decisions.
It would encourage Congress to evaluate military expenditures alongside unmet domestic needs and support serious efforts to strengthen arms control agreements and international diplomatic institutions.
Most importantly, it would place human security at the center of national priorities.
The objective should not simply be a less expensive military.
It should be a safer and more equitable society.
The Future of Security Belongs to the Public
The dispute over the Pentagon’s future is being framed largely as a contest between competing visions of military leadership and technological advancement.
But that framing is too narrow.
The American people deserve an opportunity to debate the larger direction of national security policy.
Should the United States continue organizing its economy around the expectation of permanent military competition?
Should defense contractors hold such a prominent position in shaping the nation’s technological future?
And how much public investment should be directed toward preventing conflict rather than preparing to fight the next war?
These questions cannot be answered solely by Pentagon officials, military strategists, or corporate executives.
They belong in Congress, in classrooms, in community organizations, and in public conversations across the country.
AUSA’s annual gathering demonstrates the extraordinary resources, expertise, and technological imagination available to the American military establishment.
Imagine what might be possible if comparable ambition were directed toward ending poverty, strengthening public institutions, addressing climate instability, and preventing armed conflict.
The United States does not suffer from a shortage of technological capacity.
It suffers from a shortage of political imagination about what security could mean.
The Pentagon may be battling over who will shape the Army of tomorrow.
The rest of us should be asking whether the future we want can be built through militarization at all.
