> Doolittle's raid had little/no actual strategic value.
I may be a little older than you, but I'm surprised at the number of people nowadays who don't know what actually happened in WWII. It has been over half a century now, so at most it gets a chapter in the history books, highly condensed. I had the great pleasure of reading (among other things) Admiral Nimitz's history of that war, very detailed, with a look at every decision -- juggling horribly short assets against needs everywhere.
In fact, the Doolittle Raid had a significant strategic impact -- it caused the Japanese to redistribute their forces. In particular, they strongly weakened their carrier forces in the Indian Ocean. It also strengthened Yamamoto's position in favor of the Battle of Midway, which was the turning point of the entire Pacific war. (Some revisionist historians now want to argue with that, but their heads are filled with revisionist cheese. Losing several aircraft carriers in a single battle meant that Japan would never again be able to take the initiative.) :)
I hate war. As Sherman said, "War is hell." But if you attack me, or threaten those I love, I'm a typical American: I gitterdone, the entire time wishing that you'd just kept your mind right and left me alone. I'm not saying that everyone feels that way, but I am typical.
Only those who've seen the suffering can begin to imagine how awful war is. My Veteran's Day story comes from Sandy's grandfather, who was in a foxhole in St. Vith when the Germans kicked off the Battle of the Bulge. In my eyes, he was a freakin' hero, and I begged him to talk about it.
All he would say was, "I lost a lot of friends that day." Nothing more. I felt ashamed for bringing it up, and we changed the topic.
Yes, you can argue about Korea, Vietnam, et. al. But go back and read histories written by Nimitz and others who were there. No, there wasn't a great deal of fear that Germany or Japan could actually occupy the United States, but there was still a very real possibility that Japan and Germany would win. We've gotten cocky nowadays, but back then, what with bad torpedoes, ossified admirals who didn't want to use that "newfangled" radar, planes that couldn't keep up with the Mitsubishi Zero, it was anything but a guaranteed thing.
As for the results of an Axis victory, I suggest a good dose of Turtledove or other alternative history. It wouldn't have been pretty. At all.
