so looks like no warning to the japanese people...until after the hiroshima bomb
but then also no warnings for the people of NAgasaki where the second bomb hit
i mean ifyou can trust this info...id look deeper but...the history buffs here will know for sure wont you guys....i mean it said it in your history books? is that where you learnt that you warned the people first?
keepin mind this thread isnt..why didnt japan warn its people
