Why Do people Hate the USA for the A Bombs is it because they never learned about this?

In no way does that justify any bad behavior committed by the US. I'm not saying dropping the bombs on Japan was wrong, but it reads like you think bad behavior is an excuse for bad behavior. It's not! Right is right and wrong is wrong and we all know which is which. If we are a great nation,if we are the good guys, then we have to be the good guys all the time, especially when things go bad. We can't just tell everybody what a great nation we are, we have to walk the walk.
