The history of war is the history of pain
I think what is one of the most horrible things about the World War II is the profound human suffering, that particulary civilians had to endure( like in the case of Hiroshima)
I dont want to participate to the should have or could have debates about dropping of the bomb.
Is it important to talk about it? Yes, but I think arguing about it here and insulting other posters wont really change the past.
To me its more important,
that we remember what took place during those years and teach to future generations about the horrors and history of WWII, so that we as a humanity wont repeat the same mistakes in the future.
Should US apologize? I dont know if its necessary..but showing respect to those who died is a good idea.
I sincerely hope that President Obama will visit the Hiroshima memorial in the near future and will lay some flowers there. This would send a profound message and would maybe help to heal the last remaining wounds still open in Hiroshima.
