What if the Axis had actually considered their actions in 1941 with logic?
1940's
1941: Instead of attacking the Soviet Union and starting a two-front war (which he also wanted to avoid in OTL), Hitler decides to focus all German war efforts on Britain. On December 7, Japanese planes bomb the ships at Pearl Harbor, but they also bomb the repair depots, fuel storages, and other facilities. A few days later, the US carrier fleet is also targeted out on the open ocean, truly crippling the US Navy and enabling Japan to eventually take control of the entire Pacific Ocean virtually unopposed. Emperor Hirohito somehow assures Hitler that Japan can single handedly defeat the US, persuading Hitler to not declare war on the USA.
1942: Without American military assistance against Germany, British imports suffer horribly in the Battle of the Atlantic, thus enabling Operation Sealion to even be remotely feasible. As time goes on, the feasibility of Operation Sealion increases, paving the way for the final battle between the Kriegsmarine and the Royal Navy. Meanwhile, British forces in Africa suffer major defeats, especially after Spain joins the war by attacking Portugal and providing much-needed support for Italian forces in Africa. Egypt is mostly overrun, but the job is not finished... yet. Also, Japanese forces land in Hawaii, completely securing Japanese control of the Pacific and enabling Japanese attacks on the American West Coast, especially California.
1943: Finally, after being postponed indefinitely and even cancelled, Operation Sealion begins. With the RAF and British air defenses destroyed, the Luftwaffe and Kriegsmarine go all-out on the Royal Navy, pounding it straight into the ocean while the Japanese launch a big attack in Asia a few weeks prior to distract British forces. The massive Japanese attack secures Japanese control of New Guinea, while Italian forces with German and Spanish support (especially Rommel's infamous Afrika Korps) chase the British all the way down Africa. The Wehrmacht soon secures beachheads in southern England during November and December.
1944: After securing numerous beachheads in southern England, the Wehrmacht destroys the British army with blitzkrieg tactics, which can now be used again as they are once again fighting on land. They then speed towards London, blocking any and all potential escape routes, whether land, air, or sea. The British government is then forced to sign a peace treaty, allowing Hitler to keep all his gains in Scandinavia and Western Europe, although Allied governments-in-exile are allowed to remain in British custody. Meanwhile, Italy is allowed to take most British and French colonies in Africa, but Spain gains a few small colonies as a 'thank you' for joining the war, as well as Portugal and all her colonies. In Asia, Japan is allowed to keep all her Asian conquests so far and reorganise the land however they want to, but Britain is allowed to keep Canada, Australia, New Zealand, and India. After this, the Axis is finally free to attack the United States from both sides. Also, Northern Ireland is given a referendum on whether to join Ireland or remain in the UK. They vote to remain, but Anglo-Irish tensions continue nonetheless. Finally, Japanese troops previously stationed in the Aleutian Islands begin advancing into the rest of Alaska. Hitler then considers starting Operation Barbarossa, but his generals persuade him not to.
1945: After preparing supply routes and revising strategies and tactics, the Third Reich declares war on the USA. This comes right after President Roosevelt's death, which has proved to be demoralising against the near-constant Japanese bombardments on the West Coast. Now that Britain has sued for peace, America will have to fight a two-front war against two military giants. However, fortunately for the US, the American people are willing to produce tanks 24/7 while Hitler allows the German people to only work nine-to-five.
1946: Despite stiff resistance, Japanese and German beachheads are established on the West and East Coasts respectively. Washington, DC is defended well, but US government offices are moved inland just in case. New York City is also defended, but the Stock Exchange is successfully destroyed in a German bombing raid, threatening to plunge the US into yet another economic depression much worse than the one they've just barely emerged from.
1947: Finally, with German and Japanese armies closing in on every side, President Truman sues for peace, but at a very high cost. Finally, World War 2 is over.
1950's
1950: With the Nazi-Soviet expiring the.previous year, Hitler starts Operation Barbarossa. The Soviet defense against the Nazi military juggernaut is formidable, but they are quickly pushed back.
1951: Stalingrad and Moscow fall, although Leningrad holds out against the siege. Stalin refuses to surrender, but his generals are having second thoughts.
1952: After Leningrad falls to German Wehrmacht divisions, Stalin's generals agree that the war is lost and kidnap Stalin, assassinating him while information about the Great Purge is released, invalidating decades of Stalinist propaganda. The generals negotiate surrender terms with the Germans, but the terms are harsh. Various puppet states are created in western Russia, leaving the underpopulated East vulnerable to Japanese attacks. The Neo-Soviet Union, as it is called, moves its capital to Astana and actually carries out the social equality preached by communism, especially within the military since they have a low supply of manpower.
