While many countries have exploded test weapons, only the United States has ever used Nuclear weapons against an adversary. Two bombs were dropped on two cities in Japan Hiroshima and Nagasaki in 1945, to bring WWII to an end.
These two cities belong to Japan. In ww2, nuclear weapons were used bringing total damage.
The first of the two cities destroyed by US nuclear weapons during World War II was Hiroshima, on August 6, 1945. Nagasaki was the second city to be destroyed on August 9, 1945.

The first city destroyed by U.S. nuclear weapons was Hiroshima, Japan, which was bombed on August 6, 1945. This was followed by the bombing of Nagasaki on August 9, 1945. The bombings played a significant role in bringing about the end of World War II.
It is dangerous for any country to have nuclear weapons. In the case of India and Pakistan, there has been trouble between the two countries and if a war with nuclear weapons broke out between them, it would have severe consequences.
There has not been nuclear warfare. There have been two nuclear attacks. Nuclear warfare denotes the use of nuclear weapons by both or all opposing sides. The only use of nuclear weapons in warfare were the two bombings by the US of Hiroshima and Nagasaki, and it was the intent of the US to bring WW2 with Japan to a quicker conclusion.
