The final debate of the presidential election was notable for all the areas of foreign policy on which the two candidates seemed to agree. But in their answers were plenty of unanswered questions about how they would handle key foreign policy issues going forward.
Where do things stand on Iran?
It was hard to see concrete differences between the candidates Monday on when it will be necessary to use military force against Iran's nuclear program - the so-called "red line."
Both President Barack Obama and Mitt Romney sought to portray themselves as tough on Iran and as having Israel's back. Both suggested they would be willing to use military power if necessary to stop Iran from getting a nuclear weapon. But neither was exactly clear about what point at which they would act to prevent that from happening.

CNN Fact Check: Comparing costs of Iraq, Libya missions
President Barack Obama asserted during Monday's presidential debate that it cost the United States less to help oust Libyan dictator Moammar Gadhafi than it did to run two weeks of the 2003-2011 war in Iraq.
We can attempt a comparison by examining the Defense Department's spending on the two operations.
CNN Fact Check: Romney, Obama and Iraq
Although it has been over for nearly a year now, the war in Iraq continued to be a flash point in Monday night's debate between President Barack Obama and his Republican challenger, former Massachusetts Gov. Mitt Romney.
"You say that you're not interested in duplicating what happened in Iraq," said Obama, a Democrat who opposed the U.S.-led invasion in 2003. "But 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."
But Romney, who supported the invasion, said Obama wanted to keep U.S. troops there longer - he just couldn't get the Iraqis to go along.

Sen. John McCain on Wednesday said Mitt Romney missed an opportunity to go after the president over Libya in the second presidential debate.
Asked whether Romney failed to press President Barack Obama on the administration's handling of last month's consulate attack, the Arizona senator said "in a way, he did" on CNN's "Anderson Cooper 360."
During the debate, Obama said he referred to the Libya attack as an "act of terror" the day after the violence last month. Romney disputed the claim, sparking a fiery exchange over whether the president used the term.
President Obama on Benghazi: I am "always responsible"
On Wednesday, some political observers noted Romney spent too much time over the semantics, rather than moving on and asking more questions about the security of the U.S. Consulate in Benghazi, Libya. U.S. Ambassador Chris Stevens and three other Americans were killed in the attack on the U.S. facility on September 11, 2012.

President Obama and Mitt Romney each used their second presidential debate to talk tough on China.
Romney pledged that he would label China as a currency manipulator on his first day in office - a promise he frequently works into his campaign speeches. And he accused China of "stealing" designs, patents and technology pioneered by U.S. companies.
"There's even an Apple store in China that's a counterfeit Apple store, selling counterfeit goods," Romney said. "They hack into our computers. We will have to have people play on a fair basis."
Obama was more circumspect in his use of language, but he touted the trade complaints his administration has filed against China over auto parts. Obama also recently blocked the sale of American wind farm companies to a Chinese firm.
