The bombs on Japan were, I believe definitely necessary. Talk about blockading Japan to end the war are pure fantasy - it just could not have been done. Logistically it was impossible.

Then why was it being done and why were Allied warships bomarding Japanese ports with their large guns from the sea?

For reasons I and others have posed above I believe the atomic bombs were definitely unnecessary from a military point of view as Japan would almost certainly have surrendered within weeks in any case.
