President Obama and Mitt Romney met for the third and final debate Monday night, where they tackled foreign policy issues. Below, CBSNews.com takes a closer look at the candidates' assertions on issues relating to Iraq, Russia, Iran, the size of the military, the economy and energy.

Romney's statements on Russia and Iraq

OBAMA: "Governor Romney, I'm glad that you recognize that al Qaeda is a threat, because a few months ago when you were asked what's the biggest geopolitical threat facing America, you said Russia, not al Qaeda; you said Russia, in the 1980s, they're now calling to ask for their foreign policy back because, you know, the Cold War's been over for 20 years...

"You say that you're not interested in duplicating what happened in Iraq. But just a few weeks ago, you said you think we should have more troops in Iraq right now..."

ROMNEY: "Well, of course I don't concur with what the president said about my own record and the things that I've said. They don't happen to be accurate... First of all, Russia, I indicated, is a geopolitical foe... It's a geopolitical foe, and I said in the same -- in the same paragraph I said, and Iran is the greatest national security threat we face. Russia does continue to battle us in the U.N. time and time again. I have clear eyes on this. I'm not going to wear rose-colored glasses when it comes to Russia, or Mr. Putin. And I'm certainly not going to say to him, I'll give you more flexibility after the election. After the election, he'll get more backbone. Number two, with regards to Iraq, you and I agreed, I believe, that there should be a status of forces agreement."

Romney did say in a March interview with CNN's Wolf Blitzer that Russia is "without question our number one geopolitical foe." He did mention Iran after a follow-up question from Blitzer. Here's the relevant section of the interview:

ROMNEY: ... In the new START treaty, as well as [Obama's] decision to withdraw missile defense sites from - from Poland and then reduce our missile defense sites in Alaska from the original plan, I mean these are very unfortunate developments. And if he's planning on doing more and suggests to Russia that - that he has things he's willing to do with them, he's not willing to tell the American people - this is to Russia, this is, without question, our number one geopolitical foe. They - they fight every cause for the world's worst actors. The I - the idea that he has some more flexibility in mind for Russia is very, very troubling, indeed.

BLITZER: But you think Russia is a bigger foe right now than, let's say, Iran or China or North Korea? Is that - is that what you're suggesting, Governor?

ROMNEY: Well, I'm saying in terms of a geopolitical opponent, the nation that lines up with the world's worst actors. Of course, the greatest threat that the world faces is a nuclear Iran. A nuclear North Korea is already troubling enough.

As for Romney's remarks on Iraq, he did reference in a speech this month at the Virginia Military Institute the Obama administration's failed attempts to reach a deal with the Iraqi government to keep some U.S. troops there.

Romney said in that speech, "In Iraq the costly gains made by our troops are being eroded by rising violence, a resurgent al Qaeda, the weakening of democracy in Baghdad and the rising influence of Iran. And yet America's ability to influence events for the better in Iraq has been undermined by the abrupt withdrawal of our entire troop presence. The president's tried, he tried, but he also failed to secure a responsible and gradual drawdown that would have better secured our gains."
