Damn right. And in hindsight it was absolutely the right thing to do.
And there are still those naive enough to say, "why didn't we give Japan a demonstration, so they knew what would happen?"
Well, we did give them a demonstration; it was called Hiroshima. So why did it take nuking Nagasaki to get their attention?
Setting off a nuke on some deserted atoll would have accomplished what, precisely?
