In the middle of the Civil War, Abraham Lincoln made a bold and unexpected decision: he issued the Emancipation Proclamation, freeing enslaved people in Confederate-held territories. His initial goal was to preserve the Union, not abolish slavery, but he saw emancipation as a powerful weapon against the South. It shocked many and completely shifted the nature of the war, turning it into a fight for freedom.  

2. Harry S. Truman Orders the Atomic Bombing of Hiroshima and Nagasaki (1945)

When President Truman took office, he didn’t know about the atomic bomb project. Yet, after learning of its success, he made the controversial decision to drop two bombs on Japan to hasten the end of World War II. The decision was met with mixed reactions, and to this day, it remains one of the most debated actions in U.S. history.

3. Richard Nixon Goes to China (1972)

In a dramatic move that shocked both allies and foes, Richard Nixon traveled to China in 1972, opening diplomatic relations between the U.S. and the Communist nation. A staunch anti-Communist, Nixon reversed decades of U.S. foreign policy by engaging with China, ultimately leading to a shift in the global balance of power. This unexpected decision opened the door for China’s integration into the world stage.

4. John F. Kennedy Establishes the Peace Corps (1961)

When JFK created the Peace Corps, sending young Americans to work in developing countries, it was an unexpected decision for a Cold War president. Kennedy emphasized public service and diplomacy rather than focusing solely on military power. The Peace Corps became one of his most enduring legacies, surprising many who expected him to take a more traditional approach to foreign policy.  

5. Lyndon B. Johnson Passes the Civil Rights Act (1964)

Lyndon B. Johnson, a Texan known for his strong Southern roots, made the unexpected decision to champion the Civil Rights Act of 1964. In doing so, he pushed through groundbreaking legislation that ended segregation and protected voting rights for African Americans. His commitment to civil rights was surprising given his previous political alliances and his Southern heritage.

6. Franklin D. Roosevelt Orders Japanese Internment Camps (1942)

After the attack on Pearl Harbor, President FDR made the shocking decision to order the internment of Japanese Americans. More than 100,000 people, most of whom were U.S. citizens, were forced into camps for the duration of World War II. This decision, born out of wartime fear, is now widely viewed as a dark chapter in American history.

During his presidential campaign, George H.W. Bush famously declared, “Read my lips: no new taxes.” However, in 1990, facing a budget crisis, he unexpectedly reversed course and agreed to a tax increase. This decision hurt his popularity and played a significant role in his loss during the 1992 election.

8. Dwight D. Eisenhower Sends Troops to Little Rock, Arkansas (1957)

Amid the Civil Rights Movement, Dwight D. Eisenhower made the bold decision to send federal troops to Little Rock, Arkansas, to enforce the desegregation of public schools. This was an unexpected decision from a president who had been cautious on civil rights issues. The move sent a clear message that the federal government would uphold the Supreme Court’s Brown v. Board of Education decision.

9. Barack Obama Approves the Killing of Osama Bin Laden (2011)

In 2011, President Barack Obama made the bold and risky decision to send Navy SEALs into Pakistan to kill the mastermind behind the 9/11 attacks, Osama bin Laden. The operation was highly secretive, and the decision to act was unexpected—particularly given the potential fallout with Pakistan. The successful mission was one of Obama’s most decisive moments in office.

In an unexpected turn, Theodore Roosevelt became the first sitting U.S. president to win the Nobel Peace Prize. He was awarded the prize for his role in negotiating the end of the Russo-Japanese War, a move that contradicted his “big stick” foreign policy. Roosevelt’s decision to embrace diplomacy over military force surprised many, as he had built his reputation on aggressive military stances.
