To my mind, to say that says to young people "and you probably are not going to get out of debt, and you probably do not have a climate that's going to be here come 2050." And, in my view, the point is not necessarily to win now but it's to begin building our power.

I don't want to revisit history or try to re-interpret it, you know, but starting from where we are now, given the experience that we've had in the last, you know, since 2001, which has been an utter disaster, I don't think it's benefited us. Half of our discretionary budget, right, it's like 54% of our discretionary budget right now is being spent on the military. This is not working.

In the words of Frederick Douglas, power concedes nothing without a demand; it never has and it never will. We must be that demand. We are the ones we've been waiting for.
