What was Joe Biden talking about?

What was Joe Biden talking about Sunday when he made the following comments to Democrats at a fundraiser?

"Mark my words. It will not be six months before the world tests Barack Obama like they did John Kennedy. The world is looking. We're about to elect a brilliant 47-year-old senator president of the United States of America. Remember I said it standing here if you don't remember anything else I said. Watch, we're gonna have an international crisis, a generated crisis, to test the mettle of this guy.

"I can give you at least four or five scenarios from where it might originate. ... And he's gonna need help. And the kind of help he's gonna need is, he's gonna need you - not financially to help him - we're gonna need you to use your influence, your influence within the community, to stand with him. Because it's not gonna be apparent initially, it's not gonna be apparent that we're right.

"Gird your loins. We're gonna win with your help, God willing, we're gonna win, but this is not gonna be an easy ride. This president, the next president, is gonna be left with the most significant task. It's like cleaning the Augean stables, man. This is more than just, this is more than – think about it, literally, think about it – this is more than just a capital crisis, this is more than just markets. This is a systemic problem we have with this economy.

"I've forgotten more about foreign policy than most of my colleagues know, so I'm not being falsely humble with you. I think I can be value added, but this guy has it. This guy has it. But he's gonna need your help. Because I promise you, you all are gonna be sitting here a year from now going, 'Oh my God, why are they there in the polls? Why is the polling so down? Why is this thing so tough?' We're gonna have to make some incredibly tough decisions in the first two years. So I'm asking you now, I'm asking you now, be prepared to stick with us. Remember the faith you had at this point because you're going to have to reinforce us.

"There are gonna be a lot of you who want to go, 'Whoa, wait a minute, yo, whoa, whoa, I don't know about that decision.' Because if you think the decision is sound when they're made, which I believe you will when they're made, they're not likely to be as popular as they are sound. Because if they're popular, they're probably not sound.
...
"You literally can see what these kids are up against, our kids in that region. The place is crawling with al Qaeda. And it's real.

"We do not have the military capacity, nor have we ever, quite frankly, in the last 20 years, to dictate outcomes. It's so much more important than that. It's so much more complicated than that. And Barack gets it."

O-kay.
