📖 War Record Analysis

Ronald Reagan rebuilt American military power and wielded it aggressively: the Grenada invasion, support for the Contras in Nicaragua, the Lebanon deployment (241 Marines killed), and a massive defense buildup. His administration conducted covert operations across Central America and the Middle East, often in violation of congressional restrictions (Iran-Contra). Reagan proved that military adventurism crosses party lines.
