   Manhattan Project (1939-1945):

   • The United States, along with the United Kingdom and Canada, initiated the Manhattan Project during World War II to develop atomic weapons. Scientists, including J. Robert Oppenheimer, worked on the project, leading to the successful test of the first atomic bomb in July 1945.

2. Atomic Bombings of Hiroshima and Nagasaki (1945):

   • The United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki in August 1945, leading to Japan’s surrender and the end of World War II.

3. Cold War Arms Race (1947-1991):

   • The onset of the Cold War between the United States and the Soviet Union led to an arms race. Both nations developed and tested increasingly powerful nuclear weapons, including hydrogen bombs.

4. Nuclear Energy for Peaceful Purposes (1950s):

   • The U.S. promoted the use of nuclear energy for peaceful purposes. The Atomic Energy Act of 1954 established the peaceful use of atomic energy and created the Atomic Energy Commission (AEC).

5. Limited Nuclear Test Ban Treaty (1963):

   • The United States, the Soviet Union, and the United Kingdom signed the Limited Nuclear Test Ban Treaty, prohibiting nuclear tests in the atmosphere, outer space, and underwater.

6. Nuclear Non-Proliferation Treaty (NPT) (1968):

   • The NPT was signed, aiming to prevent the spread of nuclear weapons and promote the peaceful use of nuclear energy. The U.S. and other nuclear-armed states committed to eventual disarmament.

7. Strategic Arms Limitation Talks (SALT) (1972):

   • The U.S. and the Soviet Union signed the SALT I Treaty, which limited the number of strategic ballistic missiles and launchers each side could possess.

8. Three Mile Island Incident (1979):

   • A partial meltdown occurred at the Three Mile Island nuclear power plant in Pennsylvania, leading to increased scrutiny of nuclear safety and regulations.

9. Strategic Arms Reduction Treaties (START) (1990s):

   • The U.S. and the Soviet Union (later Russia) negotiated START I and START II treaties, leading to significant reductions in deployed strategic nuclear weapons.

10. Comprehensive Nuclear-Test-Ban Treaty (CTBT) (1996):

    • The U.S. signed the CTBT, pledging not to conduct nuclear tests. However, the Senate did not ratify the treaty.

11. Post-Cold War Nuclear Policies (1990s-2000s):

    • The end of the Cold War prompted the U.S. to reassess its nuclear posture. The U.S. reduced its nuclear arsenal, and discussions focused on the role of nuclear weapons in national security.

12. New START Treaty (2010):

    • The U.S. and Russia signed the New START Treaty, further reducing strategic nuclear arsenals and including provisions for inspections and verification.

13. Modernization Efforts (2010s-Present):

    • The U.S. has initiated efforts to modernize its nuclear arsenal, including upgrading weapons systems and infrastructure. These efforts have sparked debates about the cost and necessity of such modernization.

14. Iran Nuclear Deal (Joint Comprehensive Plan of Action – JCPOA) (2015):

    • The U.S., along with other world powers, negotiated the JCPOA with Iran to limit its nuclear program in exchange for sanctions relief. The U.S. withdrew from the agreement in 2018.

15. North Korea Nuclear Crisis:

    • Ongoing efforts and negotiations have taken place to address North Korea’s nuclear program, with varying degrees of success and challenges.

The nuclear history of the United States reflects a complex interplay of military strategy, international relations, arms control efforts, and the dual-use nature of nuclear technology for both destructive and peaceful purposes.
