How Japan Forged a Postwar Alliance with the United States After Hiroshima and Nagasaki
On August 6, 1945, Hiroshima experienced the devastation of the first atomic bomb, dropped by the Enola Gay, resulting in approximately 70,000 fatalities. Just three days later, on August 9, a second bomb was unleashed on Nagasaki, claiming 40,000 lives and bringing the estimated death toll to around 200,000 by the end of the year. In a broadcast on August 15, Emperor Hirohito acknowledged the Potsdam Declaration, indicating that surrender was essential to prevent further destruction. Under the leadership of General Douglas MacArthur, Japan's new Constitution, which renounced war, was enacted on May 3, 1947. Beginning in 1946, the U.S. supplied over $2.2 billion in aid, and the Korean War further stimulated Japan's economy. The 1951 San Francisco Peace Treaty reinstated Japan's international standing, strengthening the US-Japan alliance.
