“The Air Force and the Navy carriers may have kept us from losing the war, but they were denied the opportunity of influencing the outcome decisively in our favor. They gained complete mastery of the skies, gave magnificent support to the infantry, destroyed every worthwhile target in North Korea and took a costly toll of enemy personnel and supplies. But as in Italy, where we learned the same bitter lesson in the same kind of rugged country, our air power could not keep a steady stream of enemy supplies and reinforcements from reaching the battle line. Air could not "isolate" the front. This made it a footslogger's war. To have pushed that war to a conclusion in the mud and mountains of Korea would have required more trained divisions, more supporting air and naval forces, would have incurred staggering casualties and could not have been attempted with any hope of success unless we had lifted the self-imposed tactical restrictions which gave the enemy a sanctuary north of the Yalu. I believe, however, that we could have obtained better truce terms, shortened the war and saved lives, if we had got tougher faster.”
