The uncertainty of global affairs leaves the United States questioning its future defense commitments. Questions arise about potential conflicts, such as a Chinese invasion of Taiwan, NATO allies needing defense against Russia, rising terrorism in the Middle East or Africa, or other emerging threats that could require American action.
Current federal budget constraints indicate a lack of preparedness for such unforeseen events. The present deficit suggests an engagement in a large-scale conflict, despite the intermittent military actions against Iran. Financing a prolonged war through increased borrowing could exacerbate fiscal dangers.
The deficit is a significant national security threat, echoing sentiments from 2010, when the national debt was much lower.
Throughout American history, the federal government prioritized national security. Defense once dominated federal expenditures, and wars were evident through spikes in the debt-to-GDP ratio, which later reduced. However, defense spending is now eclipsed by non-defense allocations.
Reflecting on history, in 1945 during World War II, defense accounted for 90% of federal outlays. Vietnam War levels ranged from 35% to 50%, but by 1999, post-Cold War, defense declined to 16%. Even the wars in Afghanistan and Iraq after 9/11 only nudged defense spending above 20%. Currently, defense comprises 13% of federal outlays, with projections indicating a decline to single digits by 2035. From 2032, over half of federal spending will target Social Security and major healthcare programs.
Despite this, the U.S. defense budget remains substantial, exceeding $900 billion. High wages and an all-volunteer force contribute to this. The military must remain competitive with private sector employment, avoiding a draft, which benefits personal freedom. However, volunteer reliance mandates that troop compensation forms a significant portion of the defense budget.
Approximately 40% of the Pentagon’s budget compensates military personnel or civilian staff. The U.S. military’s compensation costs are nearly quadruple India’s entire defense budget, despite India being the only larger employer globally. Military pay is legally tied to private sector raises, aligning payroll growth with economic trends.
Outdated conventional forces and nuclear deterrents necessitate simultaneous rejuvenation. The nuclear triad—bombers, submarines, land-based missiles—relies on decades-old technology. The strained Army, Navy, and Air Force require modernization, ongoing into the 2030s.
Future demands include agile drone warfare procurement, as technology ages quickly. Large numbers of drones elevate costs due to their quick obsolescence. They supplement, rather than replace, traditional weapons, presenting additional expenses in the 2030s.
The Pentagon must enhance efficiency, as it contends with bureaucracy-induced bloat. An uncompetitive defense market, reliant on limited contractors, challenges cost-effectiveness.
Defense spending isn’t the sole debt driver. The Congressional Budget Office anticipates slower defense budget growth than the economy, lowering the debt-to-GDP ratio. Yet, these projections assume peacetime and exclude ambitious proposals, like a $1.5 trillion annual defense budget.
Comparatively, the $13 billion Gerald R. Ford-class aircraft carrier costs equate to three days of Social Security spending. In 2025, military firearm purchases under 30mm cost $650 million, less than four hours of Social Security spending. The F-35 program’s long-term lifecycle cost is under Medicaid and Social Security’s $2.3 trillion expenditure last year.
Washington must prioritize national defense while managing debt prudently. Peacetime debt accumulation at extreme levels endangers national defense, counteracting fiscal responsibility.
