Sometimes, a small, seemingly meaningless decision can change everything. These butterfly effects show how tiny choices reshaped world events.
How Butterfly Effects Rewrite History
10 Elian Gonzalez Caused the Iraq War
When Saddam Hussein stood at the gallows of Camp Justice, he could not have imagined that the chain of events leading to his execution began with a tiny Cuban boy who boarded a boat bound for America. Elian González’s high‑profile custody battle ignited fury among Cuban‑American voters in Florida, swinging roughly 50,000 of them toward the Republican ticket.
George W. Bush’s 2000 victory hinged on Florida, which he won by a razor‑thin margin of 537 votes. Those extra Cuban‑American votes helped secure the Presidency for Bush, who then launched the Iraq War. Had Elian not set foot on that boat, Al Gore likely would have become President and the Iraq conflict might never have occurred.
9 Jeri Ryan Made Barack Obama President
Barack Obama’s ascent to the Oval Office can be traced back to a scandal involving actress Jeri Ryan, best known for playing Seven of Nine on *Star Trek: Voyager*. In 2004, Obama was running for a U.S. Senate seat against Jack Ryan, Jeri’s husband.
When the Ryans’ divorce papers leaked, they revealed Jack’s bizarre attempt to take his wife to a club with cages, whips, and onlookers. The public backlash forced Jack Ryan to withdraw from the race, clearing the way for Obama to win the Senate seat handily. That Senate victory set Obama on the path to become the nation’s first Black President.
8 Woodrow Wilson Ignored a Letter and Caused the Vietnam War
During the 1919 Paris Peace Conference, President Woodrow Wilson received a letter from a young Vietnamese socialist seeking a meeting. Too busy to respond, Wilson ignored the request.
The young man was Ho Chi Minh, who hoped the United States would back Vietnam’s fight for independence from France. Spurned, Ho Chi Minh turned to the Soviet Union, embraced Marxism, and later led the communist forces that split Vietnam, igniting the protracted Vietnam War. Wilson’s dismissal may have set the stage for that conflict.
7 A Bar Fight Caused Brexit
In 2012, Labour MP Eric Joyce got drunk in the Palace of Westminster’s Stranger’s Bar, shouted “too many Tories,” and began punching anyone nearby. His arrest and the ensuing scandal forced Labour to replace him.
The fallout prompted Labour leader Ed Miliband to allow anyone to join the party for a £3 fee, a move that helped Jeremy Corbyn rise to leadership. Corbyn’s tenure is widely blamed for the 2016 Brexit vote, meaning a single drunken punch helped set the United Kingdom on a path to leave the EU.
6 The King’s Speech Therapist Created Fox News
Lionel Logue, the speech therapist who helped King George VI overcome his stammer (as dramatized in *The King’s Speech*), also treated a young reporter named Keith Murdoch. Logue’s work enabled Keith to launch a successful newspaper career.
When Keith died, his son Rupert Murdoch inherited the enterprise, eventually founding News Corp and the influential Fox News channel. Fox News has swayed millions of voters, shaping American politics and even influencing elections such as the 2000 presidential race.
5 Franz Ferdinand Was Assassinated Because of a Wrong Turn
Archduke Franz Ferdinand’s 1914 visit to Sarajevo turned deadly when his driver took a wrong turn, bringing the royal car directly past Gavrilo Princip, who had been waiting for a chance to strike.
Princip seized the moment, leapt from the crowd, and fired the shots that ignited the First World War, reshaping the map of Europe and the course of the 20th century.
4 A Spokesman Made a Mistake and Brought down the Berlin Wall
On November 9, 1989, East German Communist Party spokesman Günter Schabowski was handed a note announcing a new travel‑permit policy. When asked when the change would take effect, he hesitated, then guessed “straight away.”
Citizens surged to the Berlin Wall checkpoints, and bewildered border guards chose not to use force, allowing thousands to pass. The wall effectively fell that night, paving the way for German reunification.
3 A Barber Shop’s Reading Selection Got Bill Clinton Elected
In 1962, future billionaire Ross Perot waited at a barber shop and flipped through *Reader’s Digest*, where a Thoreau quote—“The mass of men live lives of quiet desperation”—struck a chord. He quit his IBM job, founded EDS, and amassed a fortune.
Perot ran as an independent in the 1992 presidential race, capturing 18.9 % of the popular vote and siphoning crucial support from incumbent George Bush. That shift helped Bill Clinton secure the presidency, altering the political landscape for the next eight years.
2 A British Soldier’s Act of Mercy Caused the Holocaust
In 1918, British infantryman Henry Tandey chose not to fire on a wounded German soldier retreating from the capture of Marcoing. The spared soldier later resurfaced as a young Adolf Hitler, who saw Tandey’s portrait on a British propaganda poster.
Hitler reportedly pointed to the image, saying it was the man who “nearly shot me.” This admiration contributed to the Nazi regime’s propaganda, which fueled the policies that led to the Holocaust.
1 A City Councilman Killed a Dog and Created Modern Terrorism
In 1933, Texas councilman Charles Hazard poisoned his neighbor’s dog with glass shards after the animal repeatedly soiled his flower bed. The dog’s owner was 13‑year‑old Charlie Wilson, who vowed revenge.
Hazard’s re‑election campaign faltered when Wilson canvassed voters, telling the story and offering rides to the polls. Wilson’s grassroots effort helped defeat Hazard by 16 votes, launching Wilson’s own political career.
As a future Congressman, Wilson championed U.S. aid to the Afghan Mujahideen during the Soviet‑Afghan War, providing Stinger missiles that helped defeat the USSR. The resulting power vacuum gave rise to the Taliban and Al Qaeda, setting the stage for modern terrorism.
