Just because your goverment committed an act of war (justified or not) many years ago , Dunnea mean you can''t feel responsible or curious bout it.
And after all it all depends on the person visiting Hiroshima or Pearl Harbor, they could be sorry or spitefull.
There are after all loads of valid reasons to visit any war/historical sites.
Anyone behaving disrespectfull on one such site should be kicked out no matter there nationality.
