As proven by Brian Garfield in his book on the Alaskan campaign in WW2, the Doolittle Raid was a STRATEGIC VICTORY of decisive importance causing the Japanese egomaniac fascists to withhold huge amounts of forces to protect their home islands--had the U.S. Army not raided Japan lead by Colonel Doolittle, 2 Japanese carriers would not have been diverted to cover the invasion of the Alaskan islands and would have been at Midway where they would have resulted in the U.S. Navy being defeated. Midway wasn't the decisive battle of the Pacific, but it sure could have been another disaster from the Navy and marine corps. combatreform.org/midwaymyth.htm
