This document is a Secret memorandum written by Lewis L. Strauss, Chairman of the United States Atomic Energy Commission (AEC), to President Dwight D. Eisenhower on September 17, 1953. Responding to questions submitted by the President through National Security Advisor Robert Cutler, Strauss provides his assessment of two critical issues following the Soviet Union’s recent thermonuclear weapons test: the possibility of an international agreement to place fissile materials under United Nations control for peaceful purposes and the implications of Soviet advances in hydrogen bomb technology. The memorandum was later declassified.

Strauss advises that while an international proposal to place nuclear materials under United Nations supervision for peaceful purposes deserved further study, significant uncertainties regarding Soviet nuclear stockpiles and production capabilities made such an agreement impractical at the time. He also evaluates the significance of the Soviet thermonuclear test, concluding that although the available evidence remained incomplete, the Soviet Union was making substantial progress in developing hydrogen weapons. Strauss discusses the challenges of estimating Soviet production capabilities, the availability of critical nuclear materials, and the strategic implications for the United States as the Cold War nuclear arms race accelerated.
