Nagasaki a new Revelation

Watching a documentary called seconds from disaster, came to know the mentality of America and the concerned armies.
The main reason of the bombing was to test the nuclear bomb and maintaining upper hand over Soviet invasion of Japan.
Japan did not surrender because of the bomb but a choice was made to unconditionally surrender to a power who would let the imperial Japan survive than a revolution motivated Stalin ruled Soviet..  In the end innocence was lost and so did humanity.
