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.

No, there is an international agreement on banning testing, which the US observes
The atoll used by the US for nuclear weapons testing is called Bikini Atoll, located in the Marshall Islands in the Pacific Ocean. The infamous Castle Bravo test, the largest nuclear weapon ever detonated by the US, took place there in 1954.
The US performed the first nuclear weapon test on July 16, 1945.
The French conducted nuclear testing in the Tuamotu islands, on the atoll of Mururoa. The US conducted nuclear testing on the atoll of Bikini in the Marchall islands.
After the natives were convinced to move out, it was a secure area for nuclear testing. Access to the islands were controlled to hide government secrets and it was far from populated areas.
The US signed the Comprehensive Nuclear-Test-Ban Treaty in 1996 which prohibits nuclear testing. Additionally, advancements in technology allow for testing through simulations and monitoring. The US also aims to set an example for other countries to follow suit in reducing nuclear proliferation.
