Through treaties, what percentage of the land area is the U.S. committed to defend?

The United States is committed to defending approximately 50% of the land area through various treaties and agreements. This commitment reflects the nation's military alliances and obligations, particularly with NATO and other defense arrangements, which cover a significant portion of the globe. The defense treaties are meant to ensure that the U.S. can assist its allies and maintain stability in strategic regions, and this statistic encapsulates the breadth of these commitments.

The other percentages do not accurately reflect the extent of America's treaty obligations. A lower percentage would fail to capture the scope of U.S. defense commitments to its allies, while a higher percentage would overestimate the area the U.S. is obligated to defend based on current treaties and arrangements.
