The 2026 National Defense Strategy deserves credit for three important course corrections in U.S. defense planning. First, it acknowledges the overextension problem, explicitly rejecting “grandiose nation-building projects” and “cloud-castle abstractions like the rules-based international order” that drove U.S. strategic overreach and decades of endless wars, favoring prioritization grounded in American interests. Second, it returns the Pentagon to its core mission — the military instrument of national power — rejecting the previous administration’s “integrated deterrence” framework, which tasked the department with coordinating whole-of-government approaches rather than preparing to fight and win wars. Third, the strategy is more candid than its predecessors about resource constraints and simultaneity, acknowledging that the United States cannot manage concurrent conflicts alone, or even reliably deter a second adversary. These are meaningful improvements over past strategies that promised more than U.S. military power could plausibly deliver.
But despite this promising foundation, the strategy ultimately undercuts its own course corrections: It claims prioritization while expanding commitments, demands allied burden-sharing while maintaining capabilities that eliminate incentives for it, and overstates military decisiveness in ways that increase U.S. strategic risk.
The document acknowledges that “not all threats are of equal severity” and claims the strategy “prioritizes those threats of greatest consequence to our nation’s security, freedom, and prosperity.” But it immediately contradicts itself, asserting that even those threats “of lesser salience still matter and must not be ignored” and pledging to “counter the others in an effective, sustainable manner.” Rather than prioritizing, the strategy promises to do everything with different adjectives. The administration’s own actions — carrying out multiple air and missile strikes against “low priority” threats in Iran, Nigeria, Somalia, Syria, and Yemen; increasing U.S. military presence in the Caribbean; threatening military action against Greenland; and proposing a $1.5 trillion defense budget — lay bare the gap between words and action.
The strategy assumes allied burden-sharing will magically resolve these contradictions. If European allies handle Russia and Middle Eastern partners handle Iran, the United States can defend the homeland, secure the Western Hemisphere, and manage China. As the strategy acknowledges, “if our allies and partners invest properly in their defenses…together we can generate more than enough forces to deter potential opponents, including if they act concurrently.” Yet by maintaining the capability to “launch decisive operations against targets anywhere” and committing to “erecting a strong denial defense along the First Island Chain,” the United States signals that allied burden- sharing may be optional. Real burden-shifting requires limits on American commitments, leaving allies not to assume the United States will automatically provide security regardless of their defense budget.
More critically, the document never states what happens if allies and partners fail to invest. A credible strategy would explicitly prioritize, stating unambiguously that if allies underinvest and the United States faces simultaneous threats, we will defend Indo-Pacific interests first. Such clarity would both pressure allies to invest and honestly acknowledge trade-offs. Instead, the strategy maintains ambiguity, encouraging free-riding and causing its simultaneity solution to collapse if allies fail to invest.
The strategy’s confidence in “decisive operations” further undermines its realism. Operations against the Houthis were characterized as “short, sharp, and decisive,” yet lasted months, cost the loss of three F-18 fighters, and ended without Houthi capitulation. Iran’s nuclear program was claimed to be “obliterated,” yet the document later acknowledges that Iran is rebuilding. These were tactical strikes, not strategic outcomes. A strategy focused on the military instrument should honestly assess what force can and cannot achieve. Instead, this document overclaims recent results and assumes airpower can be decisive globally — closing the gap between U.S. commitments and resources. The Pentagon risks learning convenient lessons rather than correct ones — lessons that will push Washington toward more frequent interventions, creating additional risks and deepening the prioritization problems the strategy purports to solve.
In the end, the 2026 NDS articulates the right principles but adopts contradictory positions that undermine them. Until the Trump administration makes hard choices — accepting risk in lower-priority regions, honestly assessing military limitations, and creating real allied burden- shifting — prioritization will remain more aspirational than reality.
National Defense Strategy Has the Right Principles, But Fails to Follow Them
By Kelly A. Grieco
Grand Strategy
The 2026 National Defense Strategy takes important steps in the right direction, acknowledging that decades of strategic overreach, nation-building, and allied free-riding have left the United States stretched thin across multiple theaters, and that resources and simultaneity are real constraints. Yet despite these improvements, the strategy undercuts itself at every turn: It claims to prioritize the most consequential threat while simultaneously pledging to address the lesser ones; calls for allied burden-sharing while maintaining capabilities that make such sharing effectively optional; and touts recent airpower-centric operations as decisive, overstating results in ways that risk encouraging further intervention. Until Washington makes hard choices — limiting commitments, enforcing genuine burden-sharing, and accepting risk in lower priority theaters — course corrections will remain more aspirational than reality.
