Under Trump, the primary tool for projecting U.S. power is shifting from economic instruments like tariffs to direct military, intelligence, and cyber capabilities. This "Donroe Doctrine" leverages America's asymmetrical advantages in these areas, especially in its hemisphere, to achieve foreign policy wins without relying on economic coercion.

The nearly trillion-dollar US defense budget is misleading. The vast majority is locked into fixed costs like salaries, facilities, and sustaining legacy systems. The actual procurement budget for new technology is at a historic low as a percentage of GDP, constraining modernization.

A singular, massive cash infusion into the defense budget encourages buying more of today's systems, filling order books for weapons with built-in obsolescence. This approach creates a short-term 'sugar high' but fails to fund the adaptive industrial infrastructure needed for future conflicts, ultimately leading to a less capable force.

The original Monroe Doctrine was a defensive policy born from a position of weakness relative to European powers. Reframing it today as a core U.S. foreign policy pillar represents a significant scaling down of American global ambition, not a return to greatness.

The US faces a stark choice driven by its fiscal reality. It can either reindustrialize around the military-industrial complex, selling weapons to profit from global conflicts, or continue sending aid abroad, accelerating its path to bankruptcy and the collapse of domestic social programs.

Unlike past administrations that used pretexts like 'democracy,' the Trump administration openly states its transactional goals, such as seizing oil. This 'criming in plain sight' approach is merely an overt version of historical covert US actions in regions like Latin America.

The long-standing Monroe Doctrine is being superseded by a "Trump Doctrine." This new worldview prioritizes hemispheric dominance, unilateralism, and proactive intervention for specific economic and security interests (e.g., controlling immigration, securing vital assets), fundamentally changing how America views its sphere of influence.

Marco Rubio articulated Trump's foreign policy as a 'spheres of influence' model, a modern Monroe Doctrine. This framework cedes global leadership, envisioning a world where the U.S. controls the West, Russia controls its territory and Europe, and China controls Asia. This marks a fundamental shift from America's post-WWII role as a global superpower to a regional one.

A historical indicator of a superpower's decline is when its spending on debt servicing surpasses its military budget. The US crossed this threshold a few years ago, while China is massively increasing military spending. This economic framework offers a stark, quantitative lens through which to view the long-term power shift between the two nations.
