Foreign policy is generally a difficult area to fact-check - differences can be more of opinions than numbers - but that did not stop President Obama and Mitt Romney from making questionable claims:
"Just a few weeks ago, you said you think we should have more troops in Iraq right now. . . . You said that we should still have troops in Iraq to this day."
"There was an effort on the part of the president to have a status-of-forces agreement, and I concurred in that and said that we should have some number of troops that stayed on. That was something I concurred with."
Romney has the better part of this argument. Here's what he said in his Oct. 8 Virginia Military Institute speech: "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 tried - and failed - to secure a responsible and gradual drawdown that would have better secured our gains."
Romney did not technically say that troops should still be in Iraq. And he is correct: Obama did try to extend a status-of-forces agreement that had been originally signed by the Bush administration, but he could not get a deal with the Iraqi government that would have given U.S. forces immunity from prosecution under Iraqi law. So now Obama stresses the fact that he removed all troops from Iraq, while knocking Romney for supporting what he originally hoped to achieve.
"When the students took to the streets in Tehran and the people there protested, the Green Revolution occurred, for the president to be silent I thought was an enormous mistake."
Romney said Obama was "silent" on the protests in Iran, but that is not quite correct.
The president's response was initially muted - in part out of caution and in part because he was preserving the ability to relaunch negotiations over Iran's nuclear program. In that country's complex political system, the president is not the key figure. Instead, it is the supreme leader, Ayatollah Ali Khamenei, a religious leader.
On June 13, 2009, Iran announced that President Mahmoud Ahmadinejad had won reelection in a landslide victory, prompting mass protests from supporters of the main opponent, Mir Hossein Mousavi.
On June 15, with the protests becoming the largest since the 1979 Iranian revolution, Obama spoke: It is "up to Iranians to make decisions about who Iran's leaders will be," he said, adding that "I am deeply troubled by the violence that I've been seeing on television."
The president toughened his stance a week later, on June 23, after more violence erupted: "I strongly condemn these unjust actions, and I join with the American people in mourning each and every innocent life that is lost."
Obama "said by now we'd be at 5.4 percent unemployment. We're 9 million jobs short of that."
Romney likes to say that Obama promised to lower the unemployment rate to 5.4 percent by 2012. But it is not as simple as that.
Romney is citing a 14-page report, written by two Obama aides before Obama took the oath of office, concerning a theoretical stimulus bill. It was not an official government assessment or even an analysis of an actual plan that had passed Congress.
Still, the administration later cited the report in congressional testimony, giving it an official imprimatur. So, while Obama officials may not have "pledged" such a goal, it was certainly one of the administration's talking points.
"With respect to what we've done with China already, U.S. exports have doubled since I came into office."
The president has set a goal of doubling U.S. exports by 2014, but he seems to be getting ahead of himself. Exports of goods to China went from $89 billion in 2008 to $103 billion in 2011, according to the Census Bureau.
"I would say that ships that carry Iranian oil can't come into our ports."
This is a puzzling statement. No Iranian oil is coming into the United States, and none has come here for quite some time. Ronald Reagan signed an executive order in 1987 banning all U.S imports from Iran, and President Bill Clinton in 1995 banned all U.S. participation in Iranian petroleum development.
"I said if I got [Osama] bin Laden in our sights I would take that shot; you said we shouldn't move heaven and Earth to get one man."
The Obama campaign has made far too much out of this ancient comment.
Romney made this statement in a 2007 interview with the Associated Press: "It's not worth moving heaven and Earth and spending billions of dollars just trying to catch one person."
But Obama has ignored the rest of the interview, in which the AP quoted Romney as saying he "supports a broader strategy to defeat the Islamic jihad movement." Just a few days later, Romney expanded on his remarks during a debate:
"We'll move everything to get him. But I don't want to buy into the Democratic pitch that this is all about one person - Osama bin Laden - because after we get him, there's going to be another and another. . . . This is a worldwide jihadist effort to try and cause the collapse of all moderate Islamic governments and replace them with a caliphate."
"Syria is Iran's only ally in the Arab world. It's their route to the sea."
Romney says this a lot, but it is an unusual statement, considering that Syria shares no border with Iran - Iraq and Turkey are in the way - and that Iran has about 1,500 miles of coastline along the Persian Gulf and the Gulf of Oman, leading to the Arabian Sea.
Tehran certainly uses Syria to supply the militant groups Hezbollah and Hamas, but that has little to do with the water. The relationship with Syria could also effectively allow Iran to project its power to the Mediterranean and the border with Israel.
