📖 War Record Analysis

James K. Polk manufactured the Mexican-American War through deliberate provocation — ordering troops into disputed territory, then lying to Congress about Mexico shedding "American blood upon American soil." His war of conquest seized half of Mexico's territory but planted the seeds of the Civil War. Polk is the archetypal example of a president using deception to start a war of choice.

⚖️ Constitutional Authority

All 1 conflicts under Polk had congressional authorization — a constitutional record few presidents can match.

🗽 The Libertarian Assessment

Polk's military record cost 13,283 American lives and $2.5B in treasure. Every dollar spent on war is a dollar not spent on reducing the tax burden, and every life lost is a permanent cost borne by American families.
