The US is actively dismantling the global systems it created (free trade, collective security), making it the primary driver of global uncertainty, not external challengers like China.

The U.S. has a historical pattern of turning its focus back to the Western Hemisphere after periods of global overreach or crisis, such as after the Great Depression, Vietnam, and the War on Terror. This retreat is a way to reassert power in its immediate sphere of influence when its global ambitions falter.

A current US military doctrine involves intentionally starting conflicts with limited force, knowing the resulting instability will spread to allies. This compels them to "share the burden" of US national security interests, effectively forcing their involvement in conflicts they might otherwise avoid.

Luckey argues that US foreign policy is shifting away from direct military intervention. The new, more effective strategy is to arm allies, turning them into "prickly porcupines" that are difficult to attack. This approach maintains US influence and economic benefits while avoiding the political and human cost of deploying troops.

Trump’s national security strategy subtly resurrected the 'Roosevelt Corollary' of 1904. This doctrine extends the Monroe Doctrine by asserting the U.S. right to proactively change governments it dislikes in the Western Hemisphere, signaling a return to a more interventionist and sphere-of-influence-based foreign policy.

The 'Donroe Doctrine' is not a contradiction of an 'America First' platform but its logical extension. The administration's view is that the US cannot be the preeminent global power without first being the preeminent regional power. Consolidating influence in the Western Hemisphere is seen as a necessary foundation for projecting power globally.

Instead of sending aid, the US could profit from global conflicts by becoming the primary manufacturer and seller of weapons. This approach would re-industrialize the nation, create high-paying jobs in the military-industrial complex, and generate revenue without direct military intervention or sending cash abroad.

The long-standing Monroe Doctrine is being superseded by a "Trump Doctrine."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.

The administration's approach is not simple isolationism. While demanding a dominant sphere of influence in the Western Hemisphere, Trump also maintains the desire for unhindered freedom of action globally, such as mediating conflicts far from US shores. This creates a hybrid policy of 'dominance at home and freedom to roam abroad.'
