In the United States:
Lyndon B. Johnson – As the President in office during the events of the Prague Spring, President Johnson played a pivotal role in the U.S. response to the invasion of Czechoslovakia by Warsaw Pact forces, and many of the documents in this archival collection are addressed to him directly.
Dean Rusk - The Secretary of State under President Johnson. Although his tenure was dominated by the Vietnam War, he also played a key role in the United States' handling of the invasion of Czechoslovakia following the Prague Spring.
Walt Whitman Rostow – The Special Assistant for National Security Affairs to President Johnson, W.W. Rostow played a vital part in shaping how officials in the United States government viewed and responded to the Warsaw Pact forces' invasion of Czechoslovakia.
Bromley K. Smith - A Consultant to the National Security Council during the Prague Spring and subsequent invasion of Czechoslovakia.
Henry Kissinger - The National Security Advisor under President Johnson. Although primarily concerned with U.S. involvement in Vietnam, he also played an important role in the broader U.S. handling of the Cold War and pioneered détente with the Soviet Union.
Jacob D. Beam - The United States Ambassador to Czechoslovakia under President Johnson, Beam was present during the Prague Spring and subsequent invasion of Czechoslovakia. He thus served as a vital point of contact for the United States government as U.S. officials assessed the situation and decided on how best to respond.
