Obama said the magic word, and its variants, several times, in his acceptance speech last night. What am I talking about? See earlier post here. Obama:

It's a promise that says the market should reward drive and innovation and generate growth, but that businesses should live up to their responsibilities to create American jobs, to look out for American workers, and play by the rules of the road.

And:

That's the promise of America -- the idea that we are responsible for ourselves...

And:

It will require a renewed sense of responsibility from each of us to recover what John F. Kennedy called our "intellectual and moral strength." Yes, government must lead on energy independence, but each of us must do our part to make our homes and businesses more efficient. Yes, we must provide more ladders to success for young men who fall into lives of crime and despair. But we must also admit that programs alone can't replace parents; that government can't turn off the television and make a child do her homework; that fathers must take more responsibility to provide love and guidance to their children.

Individual responsibility and mutual responsibility -- that's the essence of America's promise.

And:

I will end this war in Iraq responsibly, and finish the fight against al Qaeda and the Taliban in Afghanistan.
