Why does leahy say he was against using the bomb?

Senator Patrick Leahy has expressed his opposition to the use of atomic bombs during World War II primarily due to moral and ethical concerns. He believed that the bombings caused immense civilian suffering and were unnecessary for achieving a swift end to the war, as Japan was already on the brink of surrender. Leahy also argued that the use of such a devastating weapon set a dangerous precedent for future conflicts. Overall, his stance reflects a deep concern for humanitarian principles and the long-term implications of nuclear warfare.
