"You've got to bring back the 21st century Glass-Steagall legislation and you've got to break up these huge financial institutions. They have too much economic power and they have too much financial power over our entire economy. If Teddy Roosevelt were alive today, the old Republican trust buster, what he would say is these guys are too powerful. Break them up. I believe that's what the American people to want see. That's my view."

"I think if Teddy Roosevelt were alive today, that great trust-buster would have said break them up. I think he would have been right. I think he would have said bring back a 21st-century Glass-Steagall legislation. I think that would have been right, as well. That's my view."

"I think if Teddy Roosevelt were alive today, a good Republican by the way, what he would say is: Break them up; they are too powerful economically; they are too powerful politically. And that is what I believe and many economists believe. Time to break them up."

"We should -- we should learn -- we should learn from King Abdullah of Jordan, one of the few heroes in a very unheroic place. And what Abdullah said is this is a war with a soul of Islam and that Muslim troops should be on the ground with our support and the support of other major countries. That is how we destroy ISIS, not with American troops in perpetual warfare."

TODD: Let me — let — we’re gonna — we’re staying — we’re staying basically on this topic. Obviously you’ve been emphasizing this difference on the Iraq war, but one place where you do agree, and one place where you voted to authorize the use of force, was in favor of the war in Afghanistan.

Right now, it is possible President Obama is going to be leaving the next president, perhaps President Sanders, at least 10,000 troops in Afghanistan. How long will those troops be in Afghanistan under President Sanders?

SANDERS: Well, I think our great task is to make certain that our young men and women in the military do not get sucked into never- ending, perpetual warfare within the quagmire of Syria and Iraq. And I will do my very best to make sure that that doesn’t happen.

I agree with the secretary that I think what has to happen — and let me just mention what King Abdullah of Jordan said. I think he hit the nail on the head. SANDERS: And what he said is essentially the war against ISIS is a war for the soul of Islam. And it must be Muslim troops on the ground that will destroy ISIS, with the support of a coalition of major powers — U.S., U.K., France, Germany and Russia.

TODD: Can you address a question on Afghanistan? How long are these troops going to be there? If President Obama leaves you 10,000 troops, how long do you think they’re going to be there?

Well, you can’t simply withdraw tomorrow. Wish we could, and allow, you know, the Taliban or anybody else to reclaim that country. But what we must do, and what we have seen in recent months, is some progress in Iraq, where finally the Iraqi army, which has not been a particularly effective fighting force, retook Ramadi. ISIS has lost I think 40 percent of the territory that it held in the last year.

Hopefully, and you know, one can’t predict the future, that maybe our training and their fighting capabilities are improving and we are going to make some progress in destroying ISIS.
