While many eyes are focused on Iran, the Trump Administration’s policies suggest that reasserting the Monroe Doctrine in the Western Hemisphere could rank among its highest geopolitical priorities. As laid out in the 2025 National Security Strategy, the Trump Corollary “is a common-sense and potent restoration of American power and priorities, consistent with American security interests.” What if America could project its dominance quickly, dramatically, and without firing a single shot? With one bold stroke, President Trump could expand America’s sovereign territory by nearly 20% and recover the largest unclaimed tract of land left on the planet.
Marie Byrd Land is the name for 620,000 square miles of Antarctica, a territory roughly the size of Alaska. It belongs to no nation and is governed by no sovereign power. It is desolate, largely uninhabited, and of enormous strategic importance. Claiming it would be the largest expansion of American sovereign territory since William Henry Seward’s purchase of Alaska in 1867.
The moment is right. The case is overwhelming. And the window is closing.
