@Narvik:
Now, that is pure speculation, man.
How could a great power like USA 1940 not take part in a world wide conflict about world domination and survival ?
Even with Alf Landan as president.
Would there be no war against terror if Obama was President during 911 and not Bush ?
In the 1930s the War Department of the US had the notorious color plans.
Green for a war against Mexico.
Black for a war against Germany
Orange for a war against Japan.
Red for a war against Britain.
Since may 1939, the Rainbow plans had been prepared by the Joint Army and Navy Board. This would have happened no matter if Roosevelt or Landan or somebody else was President.
I guess the only thing that could have delayed a US entry, was if Japan ignored the Pacific and attacked Russia only, and Germany ignored Britain and attacked Russia only. But of course the Great Powers USA, Britain and France could never accept this kind of new world order, so sooner or later USA would have to enter the war, at least for survival as a nation.

Shortly after Pearl Harbor, Hitler declared war on the U.S. His thought was that a state of war would allow Germany a better opportunity to sink the large numbers of American transports ferrying weapons to the Soviet Union and Britain. He thought those weapons might have made the difference between victory and defeat in the planned anti-Soviet summer offensive of '42. He also believed, probably correctly, that FDR would eventually get his wish of going to war against Germany.
I can hardly claim to be an expert on Alf Landon. But for the sake of argument, let’s suppose he was a sort of “go with the flow” politician. By that I mean a politician who isn’t afraid to hit back against an attacker, but who has no ambition to initiate aggression against any foreign nation. If he was like that, war between Germany and the U.S. wouldn’t have been inevitable; and Hitler wouldn’t have had any reason for believing it was inevitable. The U.S. would most likely have provided help to the Allies; but restraint on the part of both Hitler and Landon would have prevented that aid from degenerating into outright war.
Japan’s situation is different. Prior to Pearl Harbor, there were two schools of thought within the Japanese government. One school held that Japan should expand south, to places like the Dutch East Indies and Borneo. The other school felt Japan should expand to the north, at the expense of the Soviet Union.
The FDR administration wanted the former school to win the debate. It also wanted to promote the belief that, if Japan went to war against the colonial Dutch, it would also have to go to war against the U.S. (It was a little unclear why the U.S. would go to war to protect the Dutch colonial possessions, when it didn’t go to war to oppose the conquest of the Netherlands itself. But that’s neither here nor there.)
In order to encourage the Japanese to head south (and thereby to protect the Soviet Union from a second front), the FDR administration initiated eight separate provocations against Japan. One of them was the well-known oil embargo. Another was “pop up cruises.” These involved American warships repeatedly and deliberately violating Japanese territorial waters. The emotional effect was about the same as would have been the case, had hostile foreign ships shown up off the coast of Los Angeles or New York City. Collectively, these eight provocations caused Japanese leaders to make a decision which was part rational, part emotional. A decision to focus on the south rather than the north. And a decision to attack the United States immediately; as opposed to conquering British and Dutch colonies without declaring war on the U.S. (One of the effects of the eight provocations was to convince many Japanese leaders that a state of war between the U.S. and Japan was inevitable.)
The reason I mention all this is because the eight provocations are a fairly FDR-specific thing. They’re not the sort of thing that (for example) Calvin Coolidge or Herbert Hoover would have done. I very much doubt they’re the sort of thing Alf Landon would have done; though again I can hardly claim to be an expert on Landon. In the absence of these provocations, the Japanese would likely either have turned north against the Soviet Union, or else would have gone south without attacking the United States.
In the postwar world FDR and Churchill created, the Soviet empire stretched from the Bering Sea in the east all the way to the very heart of Germany in the west. By the late '40s, the democracies could not hope to defend Western Europe in any kind of conventional war; and would have had to immediately resort to nuclear weapons in the event of a Soviet invasion. This situation was not optimal from the American point of view, especially given the fact that the stated long-term goal of Soviet foreign policy was world conquest.
Suppose instead that the Axis nations had achieved their objectives. Hitler would have conquered all the Soviet Union west of the Urals. Germany would be at peace with the remainder of the Soviet Union and with Britain. Japan would have seized the islands of the South Pacific, as well as the eastern portion of China. In this scenario, the Old World would have four major powers: Germany, Japan, Britain, and (to a lesser degree) the Soviet Union. In a world like that, America could play these powers off against each other, as best served American interests. This scenario would give America far more opportunities to exert influence, than would a world dominated mostly by the Soviet superpower and by communist China.
Far from being helpful to American interests, the Soviet victory in WWII was very damaging. FDR was driven to take the actions he did because of ideology, not because he was working to promote the nation’s best interests. If we assume that Landon would have placed American interests above the dictates of a radical Left ideology, it becomes highly unlikely that he would have pursued a Soviet victory in WWII with the same enthusiasm that FDR did. Or even at all, for that matter.
