Chapter Ten

Defense of Democracy

World War I, World War II & the Cold War

Democracy is not self-defending. The 20th century proved this with terrible clarity. Fascism in Germany, Italy, and Japan, and totalitarianism in the Soviet Union, presented existential challenges not just to individual nations but to the idea that free people could govern themselves. America's willingness to fight — imperfectly, sometimes contradictorily, but ultimately decisively — against these threats is one of democracy's defining achievements.

This chapter tells that story honestly — including the contradictions. Japanese internment. The use of atomic weapons. McCarthyism's assault on civil liberties in the name of defending them. These are not footnotes — they are part of the full picture of what it costs and what it means to defend democracy. The arc of this chapter is not triumphant mythology. It is the complicated truth of a nation that fought for freedom while still working out what freedom meant.

Key People

The leaders, soldiers, dissenters, and ordinary Americans who defined democracy's defense.

Part One

World War I (1917–1918)

America's reluctant entry into the first global conflict — and the idealistic vision that didn't survive the peace.

Woodrow Wilson
1856–1924

28th President who kept America out of WWI for nearly three years before finally asking Congress for a declaration of war in April 1917. His Fourteen Points — the blueprint for a just peace — included self-determination of peoples and the creation of a League of Nations. Awarded the Nobel Peace Prize in 1919. Yet Wilson's legacy is deeply contradictory: he resegregated the federal government, screened the viciously racist film Birth of a Nation at the White House, and presided over the suppression of anti-war dissent through the Espionage and Sedition Acts. The man who made the world "safe for democracy" denied it to many Americans.

The world must be made safe for democracy.
Eugene V. Debs
1855–1926

Socialist labor leader who gave an anti-war speech in Canton, Ohio in 1918 and was sentenced to ten years in federal prison under the Espionage Act. He ran for president from prison in 1920 and received nearly one million votes. His case illustrates the tension at the heart of WWI-era democracy: a government fighting for freedom abroad while imprisoning dissent at home. President Harding commuted his sentence in 1921.

While there is a lower class, I am in it; while there is a criminal element, I am of it; while there is a soul in prison, I am not free.
Part Two

World War II (1941–1945)

The defining struggle of the 20th century — and America's most consequential hour.

Franklin D. Roosevelt
1882–1945

Led America through the Depression and into World War II. His "Arsenal of Democracy" speech in December 1940 began shifting American support toward Britain before Pearl Harbor. After the Japanese attack on December 7, 1941, he rallied the nation with the "Day of Infamy" address and oversaw the mobilization of American industry on an unprecedented scale. His Four Freedoms — freedom of speech, freedom of worship, freedom from want, freedom from fear — defined what America was fighting for. He also ordered the internment of Japanese Americans, one of the worst civil liberties violations in American history.

Yesterday, December 7, 1941 — a date which will live in infamy — the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.
Winston Churchill
1874–1965

Britain's Prime Minister whose defiant leadership during the darkest days of WWII — when Britain stood alone against Nazi Germany — inspired democracy's defenders worldwide. His speeches are among the greatest in the English language. His 1946 "Iron Curtain" speech at Westminster College in Missouri named the Cold War before most Americans knew they were in one: "From Stettin in the Baltic to Trieste in the Adriatic, an iron curtain has descended across the Continent." Not an American, but essential to understanding what America was defending and fighting alongside.

We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills; we shall never surrender.
George C. Marshall
1880–1959

Army Chief of Staff who built the American military from a force of 200,000 men in 1939 into an army of over 8 million by 1945. Churchill called him "the true organizer of victory." After the war, as Secretary of State, he proposed the European Recovery Program — the Marshall Plan — which rebuilt Western Europe's devastated economies and prevented the spread of communism through prosperity rather than force. The only professional soldier ever awarded the Nobel Peace Prize, in 1953.

The only way human beings can win a war is to prevent it.
Dwight D. Eisenhower
1890–1969

Supreme Commander of Allied Forces in Europe who planned and executed the D-Day invasion on June 6, 1944 — the largest amphibious military operation in history. His Order of the Day to the troops began: "You are about to embark upon the Great Crusade, toward which we have striven these many months." After the war he became the 34th President, overseeing a period of economic prosperity while managing the dangerous early Cold War. His farewell warning about the "military-industrial complex" showed a soldier who understood that military power must remain under democratic control.

You are about to embark upon the Great Crusade, toward which we have striven these many months. The eyes of the world are upon you.
The Tuskegee Airmen
1941–1946

The first Black military aviators in the United States Armed Forces, trained at Tuskegee Army Air Field in Alabama. They flew more than 15,000 individual sorties, destroyed over 260 enemy aircraft, and never lost a bomber to enemy fire on escort missions. Fighting for a country that segregated them — that denied them full citizenship — they demonstrated through courage and excellence the contradiction at the heart of a segregated democracy fighting for freedom abroad. Their service directly contributed to President Truman's order desegregating the military in 1948.

We were fighting two wars — one against the enemy abroad and one against racism at home. — Tuskegee Airman Lt. Col. Alexander Jefferson
Harry S. Truman
1884–1972

33rd President who made two of the most consequential decisions in American history: ordering the atomic bombing of Hiroshima and Nagasaki (August 1945) and launching the Truman Doctrine and Marshall Plan (1947) that defined American Cold War strategy. His decision to use atomic weapons remains deeply debated — he argued it saved millions of lives by avoiding an invasion of Japan; critics argue the bombing of civilian populations crossed a moral line. He also desegregated the U.S. military by executive order in 1948 — a landmark civil rights act made possible in part by the Tuskegee Airmen's record.

The buck stops here.
Part Three

The Cold War (1947–1991)

The long twilight struggle against Soviet communism — and the price paid at home and abroad.

George Kennan
1904–2005

State Department diplomat whose 1946 "Long Telegram" from Moscow and 1947 "X Article" in Foreign Affairs laid out the doctrine of containment — the idea that the U.S. should not try to roll back Soviet power but contain its expansion. Containment became the foundation of American Cold War strategy for 40 years. Ironically, Kennan later argued that the policy was militarized far beyond what he intended — he envisioned economic and political containment, not a global military confrontation.

The main element of any United States policy toward the Soviet Union must be that of a long-term, patient but firm and vigilant containment of Russian expansive tendencies.
Joseph McCarthy
1908–1957

Wisconsin Senator whose accusations of Communist infiltration of the U.S. government launched a wave of investigations, blacklists, and ruined careers in the early 1950s. "McCarthyism" became synonymous with the suppression of dissent in the name of defending democracy — the same contradiction seen in WWI's Espionage Act and WWII's Japanese internment. He was ultimately censured by the Senate in 1954 after CBS journalist Edward R. Murrow exposed his methods on national television. His rise and fall illustrate democracy's capacity for both self-destruction and self-correction.

John F. Kennedy
1917–1963

35th President who faced the Cold War's most dangerous moment: the Cuban Missile Crisis of October 1962. For 13 days the world teetered on the edge of nuclear war. Kennedy's combination of firmness and restraint — rejecting calls from military advisors to launch air strikes — resolved the crisis diplomatically. His 1963 American University speech called for a new approach to the Soviet Union based on mutual interest rather than mutual destruction. Assassinated in Dallas on November 22, 1963.

And so, my fellow Americans: ask not what your country can do for you — ask what you can do for your country.
Ronald Reagan
1911–2004

40th President whose confrontational approach to the Soviet Union — calling it an "evil empire" and dramatically increasing defense spending — contributed to the conditions that led to the Cold War's end. His 1987 speech at the Berlin Wall — "Mr. Gorbachev, tear down this wall!" — symbolized democratic defiance. The Cold War's peaceful conclusion under Reagan, George H.W. Bush, and Soviet leader Mikhail Gorbachev was the most consequential geopolitical event since WWII.

Mr. Gorbachev, tear down this wall!
