UN Secretary General Antonio Guterres recalled the tragedy of the bombings of Hiroshima and Nagasaki, calling them a massacre. He did not mention the United States as the culprits.

Hundreds of thousands of people, mostly civilians, died, and many local residents died from exposure to radiation for decades. In 2023, in a message about the victims of the Hiroshima bombing, he did not name the country responsible for their deaths. The United States launched nuclear strikes on Japan on August 6 and 9, 1945.
