The assassination- Giuseppe Zangara was an angry, discontented person who felt angry at the government for his poor condition and his acute abdomen pains started to drain his mental health. On the 15th February 1933 before he was inaugurated FDR was going to give an impromptu speech from the back of an open car in Miami, Florida. Zangara decided to take his rage out on FDR by buying a pistol. Zangara took his seat where Roosevelt was going to give his speech but due to his short height he couldn't see over the hat of the woman in front of him. He stood on his chair, which was wobbly, and his five shots all missed Roosevelt. A woman wearing a hat saved the life of FDR. In this scenario that woman (Lillian Cross) does not wear a hat so with a clear shot Zangara shoots FDR. The President elect dies of his wounds on the way to hospital. Like in our timeline Zangara is executed to death on the 20th March (in our timeline he shot the Chicago mayor Anton Cermak who was travelling with FDR). On March 4th instead of Roosevelt being inaugurated his would be vice-President John Nance Garner is sworn in as President.
Post-war era- Japan would remain the major power in Asia following the war having puppet nations in China, Indochina and Indonesia as well as conquered land in the Pacific. Quite likely the US would grant the Philippines its independence in order to keep independence movements from siding with the Greater East Asia Co-Prosperity Sphere (an economic unity of Asia countries under a Japanese empire that never came to fruition in our timeline). Post-war Europe would resemble our timeline except Germany would be split directly between France, Britain and Germany although with slightly altered spheres of influence which would form East and West Germany following Cold War tensions. A form of NATO would be made to challenge the perceived threat of the USSR but Britain and France would be the main players. Similarly Britain and France would embrace their former enemy of the Japanese Empire as the Cold War escalates. The USSR would detonate its first nuclear bomb in 1948 with Britain, France and Japan detonating their own by 1953; something that the USA would also copy in the 1960s as it starts to branch out of its traditional sphere of influence of the Americas. The Cold War in Europe, Africa and the Middle East would remain the same but in Asia Japan would be facing guerrilla warriors fighting for total independence who will be funded by Britain, France and later the USA fearing that some like Ho Chi Minh's Viet Minh would want to install communist states. However with Japanese influence on the mainland Mao Zedong's communist guerrillas would take until the eventual collapse of the Japanese Empire in the early 1970s to install a people's republic while Mao's bitter rival Chiang Kai-Shek would die in exile in the USA.
Domestic USA- As there was no four consecutive terms for FDR there would be no 22nd Amendment limiting a President to two terms. Wallace would be seen as a mediocre President serving two terms and minor social reforms but with an abysmal foreign policy record by allowing the USA to be sidelined by two empires (Japan and Britain) and communists (the USSR) on the world stage. Civil rights though would be pushed back decades. Although FDR did relatively little for civil rights with legislation because he was either disinterested or had his hands tied by a reluctant Congress his impact greatly aided civil rights. The Indian Reorganization Act allowed Native Americans some brief respite while Eleanor Roosevelt's actions helped increase awareness of the rights for African-American and women. Roosevelt creating the National Labor Relations Board helped A. Philip Randolph lead the civil rights movement by propelling him to cultural significance and through him there was Martin Luther King's March on Washington in 1963 (King got the idea based on an abandoned march idea that Randolph had). It was Randolph who pressured Roosevelt into creating the Fair Employment Practice Committee to end employment discrimination in the government and FDR's talks with the NAACP undoubtedly strengthened it. No FDR meant no Truman who desegregated the army and FDR appointed more liberal judges to the Supreme Court (although originally he tried to put more judges in the Supreme Court to get what he wanted passed) which set off a trend of pro-civil rights verdicts such as Gaines v. Canada which let an African-American go to a white school. The US involvement in the Second World War let Dwight Eisenhower later to be easily made the Republican candidate and when he was President he made Earl Warren Chief of the Supreme Court who helped civil rights such as with Brown v. Board of Education which declared education segregation unconstitutional and Miranda v. Arizona which created the Miranda rights. Eisenhower even enforced desegregation at Little Rock, Arkansas by using the National Guard to escort African-American students into a white school. When Lyndon Johnson becomes President whether the Jim Crow laws are downed in one fell swoop with the 1964 Civil Rights Act (which would have to include transport, education and army desegregation) or whether each Jim Crow law had to be challenged individually it is hard to tell.
What do you think the world would be like if FDR was assassinated? Do you think the world would be better, worse or the same? Do you think I'm talking rubbish and are fawning over FDR or is some of what I'm saying seem somewhat plausible? Please leave your opinion and next week it'll be the first anniversary of the blog! I'll be doing a redux of one past alternate history scenario. I'll give you a clue about what it's about: a series of unfortunate events allowing a homicidal racist with a mustache to crush the world under his boot...
