Which President? US or UK. Since US is the first country to use nuclear weapons, then I assume that you are asking who was the US president during world war two while nuclear testing? Answer: Truman.

The United States of America
The U.S. is first to have nuclear weapons, having nukes since 1945. The Soviet Union followed the U.S. by developing and testing their first nuke in 1949. Both nation started making hydrogen bombs (nukes using nuclear fission to explode) starting in the mid-1950s. Excuse me replying with a question, but were the Atomic bombs dropped on Japan in 1945 Nuclear weapons ? I am assuming they were, but do not know of the differentiation.
India conducted its first nuclear weapons test, codenamed "Smiling Buddha," on May 18, 1974. This made India the first country outside of the five permanent members of the United Nations Security Council to possess nuclear weapons.
The United States of America was the country that developed the first nuclear weapons.
The first Islamic country to have nuclear weapons was Pakistan.
