And there was lots more than we thought to the late Gen. Douglas MacArthur. Author Joe Goulden dug through mountains of private papers for his hot new book, "Korea: The Untold Story of the War." Joe says that when Harry Truman fired MacArthur in '51, the general summoned his replacement, Gen. Matthew Ridgeway. He confided that the president was sick. MacArthur had been told by a top medical man, he said, that Truman suffered from "malignant hypertension." The affliction was "characterized by bewilderment and confusion of mind." To the implication that Truman was dotty, he added darkly that the president "wouldn't live six months." (Truman died in '72, eight years after MacArthur) . . . And, Joe says, way back in the '30s, MacArthur himself had fits of despondency. He would summon a military aide to his side, before pointing a loaded pistol at his own temple. The aide, Lt. Thomas Jefferson Davis, would point out that MacArthur's death would be too great a loss for the country to stand. Then, it would all blow over 'til the next time. Ear, luckily, was too young to have illusions then, and is too old to have them now. A happy state of affairs.
