Yep. And it took an atom bomb to do it. I'm glad they did, but if they had not, it would have been at least 2 more years of bloody fighting. And we also occupied Japan with many troops for many years after. Afghanistan (where all empires fail...remember) fell in weeks. Baghdad fell in weeks. Now we are in the occupancy stages of both countries and will be for a couple more years. Looks damn successful to me.
When I can get on a plane carrying my Leatherman, and visit the Smithsonian without having my camera bag searched, and the traffic barriers come down in front of the White House, that's when I'll agree we've won the war.
Change years to decades....
