Do you think atomic bombs should be considered an option for modern warfare?

No. They have unacceptable humanitarian consequences and pose a threat to humanity. The simple reality is that the international community could never hope to deal with the impact of nuclear weapons use. It is not necessary . Militarily Japan was finished (as the Soviet invasion of Manchuria that August showed). Further blockade and urban destruction would have produced a surrender in August or September at the latest, without the need for the costly anticipated invasion or the atomic bomb.

This is also a question asking for your opinion, so there is no right or wrong answer.
