JONES: Well, I think that's -- I think Yemen is very worrisome. This is a -- Saleh has been very skillful over the years in being able to consolidate and maintain his power. The trends in Yemen are not good. And this could be a major problem. And where terror is concerned, this would be a safe haven that would be a very troubling turn of events for us.
AMANPOUR: So is the U.S. to try to keep Saleh in power or what?
JONES: Well, I don't know -- you know, there are certain things that we can do and that we can't do. When events reach a certain stage, they have a life of their own. And it would be nice to be able to think that we could do everything and make the world, you know, perfect the way we want it. But that's not the case.
So the trendlines in Yemen are not good. We've invested a lot of work in Yemen. But it is a disturbing trend for the future. And this is -- again, one of the things that I feel strongly about is that when you look at what's going on in this part of the world and you look at the potential, there is reason to be optimistic in some areas and there is reason to be very concerned in others.
But it's a tremendous tectonic shift in terms of the world as we know it, and this part of the world since -- for the last 80 years.
AMANPOUR: General Jones, thank you very much, indeed, for joining us.
And what do you think the U.S. should do next in Libya? Tweet me, @camanpour #libyanext.
Meantime, the costs of the new war are already piling up. More than half a billion dollars so far. All this as Congress and the White House remain at loggerheads over a federal budget, and a government shutdown is looming.
The deadline just five days off. Will lawmakers beat the clock? We'll hear from one of the Democrats' toughest negotiators, Senator Chuck Schumer, and the top Republican on the Budget Committee, Jeff Sessions. That's in a moment.

REP. JOHN BOEHNER, (R) OHIO: I have never believed that shutting the government down was the goal. And frankly, let's all be honest, if you shut the government down, it will end up costing more than you save because you interrupt contracts -- there are a lot of problems with the idea of shutting the government down. It is not the goal.

AMANPOUR: House Speaker John Boehner, the man in the middle this weekend, caught between a rowdy freshman class of hardline conservatives and the more moderate congressional Republicans who want to deal.
Boehner, of course, wants a deal, too. But as senior political correspondent Jon Karl tells us, it's hard to broker compromise in a town where compromise itself has become a dirty word.
CROWD: We want it back. We want it back.
JON KARL, ABC NEWS CORRESPONDENT: Compromise on spending cuts? Not if these folks have anything to say about it.
UNIDENTIFIED MALE; It's time to pick a fight.
UNIDENTIFIED MALE: Because if we don't, we deserve to be thrown out of office.
REP MIKE PENCE, (R) INDIANA: Liberals in the Senate would rather play political games and shut down the government instead of making a small down payment on fiscal discipline and reform. I say, shut it down.
KARL: That was at a Tea Party rally on Capitol Hill where one organizer had this message for GOP leaders.
