In modern South Korea, practicing shamans worship a 20th-century American general as a literal deity, building shrines and seeking his guidance from beyond. This episode opens a comprehensive encyclopedia source to understand how Douglas MacArthur engineered himself into a mythological force while still alive, and how a man who championed a new constitution, democratization, and the breakup of corporate monopolies in occupied Japan carried an ego so monumental it ultimately collided with civilian control of the American military.

The story runs from his Medal of Honor father Arthur MacArthur and his mother ‘Pinky’, who kept him in curls and skirts until age eight and moved into a hotel overlooking West Point, through a rogue 1914 reconnaissance shootout at Veracruz, the Rainbow Division and becoming the youngest general in the AEF at 38, the Bonus Army debacle, the PT boat escape from the Philippines and the promise to return, island hopping, accepting the surrender aboard USS Missouri, the Incheon landing, and his firing after pushing toward the Yalu River and telling foreign diplomats he would handle the war his own way.

• Why his Veracruz medal nomination was denied: commanders feared rewarding young officers who ignored the chain of command
• The World War I theatrics of refusing a helmet and gas mask and returning from no man’s land as sole survivor, and whether that was morale-building leadership or toxic bravado
• The secret payoff to two journalists threatening to expose a mistress, and insisting on being the first recipient of the Purple Heart he had revived
• How his belief in his own historical destiny, rather than egalitarian ideals, may explain his benevolent rebuilding of Japan and his rejection of racial superiority
• ‘MacArthurism’, the ticker-tape parades after his firing, and his later advice to two presidents against land wars like Vietnam and for a naval blockade during the Cuban Missile Crisis
