LeMay presidency... not much of civilization outside US would be exist by the time he leaves the office.
LeMay gets an enormously bad rap.
What was his job in the military, WHILE UNDER ORDERS of superior officers, in WW II? Oversee and command the Bombing Offensive to destroy an enemy with which the U.S. was in a DECLARED state of War using any and all weapons placed at his disposal. He followed those orders, didn't hop around with joy over them or go on newreels proclaiming how well his "dehousing" campaign was going. He found a manner to follow his orders (including, unlike certain other Commanders of Bombing offensives, diverting more than half of his assets to a sea mining campaign that burned down not a single structure, but crippled a vast part of the Japanese economy), vastly reduce losses to the men under his command, degrade and deny the enemy of its ability to wage war and by doing so was a major part of the reason that Operation Downfall never took pla. By doing so he saved, at minimum 400,000 American Lives, minimum 800,000 civilian lives in Japanese occupied areas of Asia (assuming the entirety of Downfall was 8-9 months in length), minimum 500,000 Japanese military KIA (like x3), and a minimum of 3 MILLION additional Japanese civilian fatalities.
What was his job as Commander of SAC (again, while under orders of bother superior officers and the civilian National Command Authority)? Create, equip, and train a strategic nuclear force capable to utterly destroying the enemy IF and only IF given orders to proceed by the NCA. What was the slogan he gave to Strategic Air Command?
Peace is our Profession. He, and probably 98% of the personnel under his command (there are a few sociopaths in any group) woke up every morning and prayed that they would never have to do the job that they were trained for, and went to bed every night thanking God that they hadn't been forced to carry out their assigned task while on duty that day. They all did that for YEARS, if not decades. They stood at the Sharp End and faced the Soviet threat. By doing sp, following LeMay's training and procedures , they ensured that the only two cities on Earth to suffer the horror of a nuclear attack were destroyed in 1945, despit the fact that the total number of nuclear wepons in the world at one point approached 70,000, none were ever used after that terrible 9th of August morning in 1945.
LeMay was a profession soldier. You will never find a person who despised war more than a professional soldier.
