Perhaps you should read the article again, specifically the part about our demand for unconditional surrender:

“Sun Tzu once said, “When you surround an army, leave an outlet free. Do not press a desperate foe too hard.” In 1943, President Roosevelt violated this maxim with his demand for unconditional surrender by the Axis powers. Instead of allowing any possibility of ending hostilities by diplomacy, he literally left the German and Japanese high commands with the choice of victory or death; either defeat the Allies or hang after capture, defeat, and trial. The impossibility of a negotiated peace is likely the single greatest factor in Japan’s refusal to surrender to the overwhelmingly superior American armed forces.”
