Different outcomes for specific events, such as the impact of hypothetical Axis victories in the Battle of Britain, Moscow, Lenningrad, Stalingrad, Suez, Midway, Leyte, Normandy, etc are to me legitimate things to discuss, but it would take Axis victories in virtually every key battle fought in WW2 to knock Britain and the USSR out of the war (a complete fantasy)......... and you still have the USA surviving in North America protected by the ocean, outproducing the world, and the largest fleet in the world. There is simply no logistical way Japan or Germany could invade the US.
Reading the sample chapters from book referenced in the OP, my quote above seems to be the premise: that a number of Allied victories (or less-than-worse defeats) were near run things that could have gone in The Axis's favor, and that such defeats could have altered other calculations - not that it would have inevitably led to an Axis victory but that it could have. Also the author (correctly, in my opinion) pins a lot on human error - mostly on the Axis's part. However, evoking "what ifs" about smarter German or Japanese political leaders and field commanders is a parlor game that opens all sorts of butterflies. If Tojo, Nagumo, Hitler, or Goering make better decisions they are different people. What made them different people? Would the events that made them different people change other things as well? I'm much more comfortable with evoking simple bad luck or non-ASB "acts of God" like storms or earthquakes for "what-ifs".
I fully accept the premise that Britain could have been defeated or neutralized by Germany in 1939-40, but a war that ended in late 1940 with Britain accepting some sort of armistice or even just deciding finally to sit on its hands if Hitler just "declared peace", would not be WW2. For that matter even a European War that ended with a sucessful Operation Sealion (I know, I know) would not be WW2. There would no doubt be another war eventually involving the USA and the USSR and that's the war Germany could never win (survive, possibly) but not win.
Once the USSR was invaded, the only way Germany realistically could have won would have been if they weren't Nazis... ie: actually come as liberators to free people from Stalinist and Collectivist terror. As others have noted, the racist Nazi nature of the German regime must be considered a given in any realistic WW2 scenario...that's more basic than military and production strategies. The people of the USSR soon realized they were fighting a war for individual and cultural survival and in that situation, it is basically impossible for Germany to win that war.
In the Pacific, I just don't see a way Japan could parlay any conceivable series of military victories and brilliant strategic decisions in 1941-43 into a situation where Japanese troops would be raisinig the rising sun flag in Los Angeles or even Sydney. In the Pacific, Japanese "victory" is only possible if the US was willing to negotiate and the attack on Pearl Harbor made this a political impossibility
And as others have said, there is the Manhattan project to consider. Once the bomb is developed, Allied (or US) victory is inevitable.
