Bye Bye Miss American Pie? Why the America Century Rolls On

Mark Twain once quipped that rumors of his death had been greatly exaggerated. Similarly, recent obituaries declaring the demise of American global primacy appear to be premature upon closer examination of the foundations of U.S. power. Recent discourse on the future world order has centered on concepts like multipolarity, China catching up to the US, and post-Americanism. However, assessing the fundamentals of power, what is revealed is that the United States remains the sole global superpower upholding the liberal international order it created after WWII. America possesses structural advantages in multiple dimensions of power that are unparalleled, despite facing greater counterbalancing efforts. Let us look at America's enduring edge in military, economic and geopolitical strength that preserve its unipolar position in the world order.

Military Supremacy The United States maintains a substantial lead in military power through its unmatched scale, technological sophistication and global power projection capabilities. With a defense budget exceeding $800 billion annually, America spends more on its military than the next nine highest-spending countries combined, including rivals like China and Russia!

The US armed forces have over 1.4 million active personnel across five branches including the world's largest air force and second largest navy. It fields cutting-edge weaponry like 5th generation F-35 stealth fighters, Ford-class carriers with electro-magnectic catapults, Virginia-class nuclear powered submarines, and advanced missile defense systems. Russia is the only other military that comes close in terms of high-tech weapons inventory.

Crucially, the US military is able to rapidly deploy and sustain large forces anywhere in the world leveraging its vast network of overseas bases, naval carriers, strategic airlift capabilities and pre-positioned resources. The US Pacific Command alone covers half the earth's surface and has around 200,000 troops and five aircraft carrier strike groups. This global power projection combined with technological prowess enables the US to dominate in any conventional conflict.

Cyber and space are emerging as new domains of critical advantage where the US is ahead of strategic competitors. America's sophisticated intelligence and surveillance apparatus comprises assets like spy satellites, drones, and advanced SIGINT giving her unparalleled situational awareness and targeting capability. Its tight integration with the worlds' largest defense industry and R&D complex further enhances its ability to find, fix and finish threats rapidly.

The US nuclear arsenal with around 4000 warheads provides the ultimate insurance against existential threats. While Russia has similar numbers, the US stockpile is more modernized especially in missile defense systems and diversity in delivery platforms by air, land and sea augmenting America's second-strike deterrence. Allies in NATO and Asia host US nuclear weapons further adding regional deterrence. No adversary is able to overcome US nuclear supremacy in the foreseeable future! Finally, America's network of alliances and bases globally creates a force multiplier effect. Interoperability with allies like Britain, Japan, Israel provides technological access and shared intelligence. US-led security architectures like NATO enable coalition warfare capabilities. The US leverages local partners but largely dictates terms given her strength .

In sum, the US has continued to build on its conventional and strategic military predominance accrued since the Cold War. With rising challengers like China, modernization and innovation in emerging warfare domains will be critical. But America stays atop an unassailable position in combined resources, technology and global reach.

Economic Strength America's economic capacity provides the vital underpinning for its hard power and broader leadership credentials. The US has the world's largest and most productive economy at around $23 trillion in GDP. Per capita income over $63,000 is five times more than China’s reflecting a more advanced economy with greater productivity.

America's key strength lies in her continued lead in higher value-added and future-oriented sectors like technology, financial services and intellectual property. US tech firms account for over 70% of global digital ad revenue. American banks control nearly half of all global asset management activity. In 2021, US-headquartered multinationals generated $8 trillion in revenue from overseas operations and investments. Overall, foreign affiliate income is four times larger than China's. The US continues to dominate capital markets and the global financial system amplifying its structural power. It accounts for over 40% of global pension funds, 60% of global private equity funds and the world's 20 largest hedge funds. US stock markets on Wall Street with over $50 trillion in market cap remain the primary source of equity financing for globally ambitious firms. Underpinning this is the exorbitant privilege accruing from the US dollar being the dominant global reserve currency. Over 60% of the world's foreign exchange reserves and overseas transactions use the dollar. This provides macroeconomic flexibility to use fiscal and monetary levers for domestic priorities. It also enables imposing strong secondary sanctions globally as transactions are primarily dollarized. America spends the most on R&D and attracts the largest share of global venture capital in cutting-edge fields. US higher education remains a magnet for the world with 8 of the top 10 global universities located in America. Leading companies leverage America's deep talent pool including immigrants and the world's best minds, powering innovation. This innovation ecosystem and intellectual property protections incentivize risk-taking. This not to say that China and India are not catching up, but the US retains an edge in high-tech patents and development of emerging technologies like AI, quantum, nanotech, and biotech. American firms lead in cloud, e-commerce, payments, and platform business models of the future. India has promise but punches below its weight. Hence, the US remains well-positioned to dominate the knowledge economy. There are though rising concerns like inequality, polarization and fiscal deficits that could hamper America's social contract and economic dynamism. Managing the political economy strains of globalization requires urgent reforms. But the foundational pillars—free enterprise culture, strong institutions, vibrant capital markets—provide American business the natural ecosystem to thrive. Geopolitical Leadership America's economic and military might provide the hard power foundations for its soft power and global leadership. But equally important is the ability to shape international politics, norms and rule-setting. The US constructed the post-WW2 liberal order including institutions like the UN, IMF, World Bank that still underpin the current system. Despite the rise of new powers, the Western-led order retains legitimacy and appeal for much of the world. Power transitions are rarely smooth, but US support for the existing order garners broad multilateral support. Most countries do not wish to overhaul the system and start anew. They prefer reforming existing structures. Hence, the US continues to lead in shaping responses to global challenges ranging from financial crises and climate change to nuclear proliferation. Formal US alliances in Europe and Asia remain indispensable pillars of regional stability that partners are reluctant to abandon. America uses both hard military assets and soft power tools like diplomacy, foreign aid and cultural influence to sustain its leadership. Rivals like China and Russia have demonstrated neither the intent nor appeal to craft an alternative global order. China prefers reaping the benefits of the US-built system for its own rise rather than undertaking the burdens of leadership. Russia's disruptive behavior wins few backers. Hence, despite diffficulties, the US remains the chief steward of the international system.

Critics contend that failures in places like Iraq, Libya and Afghanistan signify imperial overstretch and decline reminiscent of past hegemons like Rome. But American power has shown resilience and renewed its underpinning support from allies. Its domestic institutional strength provides stability that authoritarian challengers lack. However, there are clear limits to unipolarity. India, EU, and Japan need to share more burdens. Emerging domains like cyber and space require new rules. Containing China's bid for regional hegemony could become the defining test. Much depends on revitalizing the US domestic social contract and economy. But American leadership, for all its flaws, still anchors the international system. Assessing the pre-eminent indicators of power – military capacity, economic strength, and geopolitical leadership – demonstrates that the United States maintains substantial advantages over other contenders. It retains the multidimensional attributes of a global superpower that is yet unmatched by either rivals or a coalition of emerging powers. This does not imply unchecked US hegemony. Power is increasingly contested and constrained. But the world order remains unipolar and dependent on enlightened American leadership. The demise of US exceptionalism is exaggerated and American unipolarity could endure for decades more as the pillar of global stability.
