'In May of 1945, the architects of postwar strategy, or, as they liked to  call themselves, the "Masters of the Universe", gathered in San Francisco at  the plush Palace Hotel to write the Charter for the United Nations. Several  of the principals retired for a private meeting in the exclusive Garden  Room. The head of the United States delegation had called this secret  meeting with his top aide, Alger Hiss, representing the president of the  United States and the Soviet KGB; John Foster Dulles, of the Wall Street law  firm of Sullivan and Cromwell, whose mentor, William Nelson Cromwell, had  been called a "professional revolutionary" on the floor of Congress; and W.  Averill Harriman, plenipotentiary extraordinary, who had spent the last two  years in Moscow directing Stalin's war for survival.

These four men  represented the awesome power of the American Republic in world affairs, yet  of the four, only Secretary of State Edward Stettinius Jr., had a position  authorized by the Constitution. Stettinius called the meeting to order to  discuss an urgent matter; the Japanese were already privately suing for  peace, which presented a grave crisis. The atomic bomb would not be ready  for several more months. "We have already lost Germany," Stettinius said.  "If Japan bows out, we will not have a live population on which to test the  bomb."
 
"But, Mr. Secretary," said Alger Hiss, "no one can ignore the terrible power  of this weapon." "Nevertheless," said Stettinius, "our entire postwar  program depends on terrifying the world with the atomic bomb." "To  accomplish that goal," said John Foster Dulles, "you will need a very good  tally. I should say a million." "Yes," replied Stettinius, "we are hoping  for a million tally in Japan. But if they surrender, we won't have  anything." "Then you have to keep them in the war until the bomb is ready,"  said John Foster Dulles. "That is no problem. Unconditional surrender."  "They won't agree to that," said Stettinius. "They are sworn to protect the  Emperor." "Exactly," said John Foster Dulles. "Keep Japan in the war another  three months, and we can use the bomb on their cities; we will end this war  with the naked fear of all the peoples of the world, who will then bow to  our will".'
