UPDATE AT 10:27 P.M. (AP) -- Republican Mitt Romney is backing President Obama's plan to pull American troops out of Afghanistan by the end of 2014.
Romney says the Afghan troop surge that Obama ordered has been successful and a training program for Afghan forces is on track. As a result, he says the U.S. will be able to make a transition at the end of 2014 and make sure U.S. troops come home.
The Republican nominee has previously criticized Obama for setting a timeline for ending the war.
Obama tripled the number of U.S. troops in Afghanistan upon taking office. He has said the U.S. will maintain a civilian presence in Afghanistan after its military operations end.
UPDATE AT 10:26 P.M. (AP) -- President Obama is pushing back on rival Mitt Romney's suggestion that the president has apologized for the United States on the world stage. Obama called the accusation the "biggest whopper" of the campaign.
The two men were sparring over foreign policy Monday in the final debate before Election Day.
Obama said he would not allow Iran to develop a nuclear weapon and had coordinated an international coalition to impose economic sanctions on Tehran. Obama said that under his presidency, the world is more united and Iran has been weakened.
Romney insisted Obama had apologized for the U.S., noting the president had given a speech in Egypt early in his term saying America had been "derisive" and at times had dictated to other nations.
UPDATE AT 10:06 P.M. (AP) -- President Obama says the United States will stand with Israel if it's attacked.
Obama said during Monday's presidential debate that Iran will not get a nuclear weapon "as long as I'm president."
Republican challenger Mitt Romney says he'd push for diplomatic isolation of the country. He says Iranian President Mahmoud Ahmadinejad's rhetoric fans genocide and should be prosecuted under international law.
Obama says tough U.S. sanctions have "crippled" Iran's economy to the point that it's a shambles. The president says Iran is ultimately a threat to American national security and is a state sponsor of terrorism.
UPDATE AT 10:05 P.M. (AP) -- President Obama says his military spending is "driven by strategy" not by politics.
The president is rejecting criticism from Republican Mitt Romney, who says Obama wants to cut the military by $1 trillion. Obama disputed that figure, but said spending needs to be based on the capabilities required by the military, not just budgets.
Obama accused Romney of calling for increases in military spending that the Pentagon doesn't want.
Romney says he would boost the number of naval ships because the U.S. fleet is the smallest since 1917. The president shot back, saying that was because technology has changed the nature of the military.
Romney said he would pay for increases in military spending by getting rid of Obama's health care overhaul and other programs he deems unnecessary.
UPDATE AT 9:55 P.M. (AP) -- Presidents Obama and Republican Mitt Romney are shifting their debate on foreign policy toward domestic issues that are foremost on voters' minds.
Obama turned questions during Monday's third and final debate around and made them about jobs and the economy. Romney, too, pivoted from foreign policy questions to his five-point domestic agenda for jobs and the economy.
At one point, debate moderator Bob Schieffer seemed exasperated. "Let me get back to foreign policy," he pleaded.
Obama answered one foreign policy question by talking about his education initiatives and criticized Romney's tenure as Massachusetts governor.
Romney, too, detoured stateside. When asked about America's role in the world, he shifted the talk to college students who are graduating without jobs.
UPDATE AT 9:54 P.M. (AP) -- President Obama and Republican Mitt Romney are outlining different visions of the U.S. role in the world.
The two men were debating foreign policy Monday in the final debate before Election Day.
Romney said the U.S. has the "responsibility and privilege" to promote peace throughout the world. But he said domestic issues like the sluggish economy and debt had weakened U.S. leadership.
Romney said he would not cut military spending as president and would work to strengthen international alliances.
Obama said the U.S. was the "one indispensable nation" in the world and is stronger now than when he took office. He said the U.S. should rebuild its economy by keeping jobs in the country rather than shipping them overseas.
UPDATE AT 9:38 P.M. (AP) -- President Barack Obama is taking an aggressive posture toward rival Mitt Romney in Monday's debate, at one point saying the Republican's policy proposals are so outdated "the 1980s are now calling to ask for their foreign policy back."
The two sparred early in the debate moderated by CBS News anchor Bob Schieffer.
After Romney voiced concerns about the persistent threat of al-Qaida in the Middle East, Obama noted Romney had once called Russia the nation's gravest geopolitical threat.
Obama said Romney's policy positions were rooted in the 1980s and his views on social issues are rooted in the 1950s.
Romney said he wouldn't have "rose-colored glasses" toward Russian leader Vladimir Putin and chided Obama for suggesting he would have greater flexibility toward Russia after the election
UPDATE AT 9:37 P.M. (AP) -- President Obama and Republican Mitt Romney say they are both opposed to sending U.S. troops to Syria to end the violence there.
Obama says that while attacks by government forces against Syrian citizens is heartbreaking, getting the U.S. "entangled militarily" would be a serious step. Romney essentially agreed, saying he doesn't want the U.S. military involved in Syria.
Romney said the United States should be playing a leadership role in identifying responsible opposition groups in Syria and making sure they have the arms they need to fight President Bashar Assad's regime.
Obama says the U.S. is working with allies in the region to learn more about the opposition. But he says giving heavy weapons to those groups is not "a simple proposition."
UPDATE AT 9:26 P.M. (AP) -- Republican Mitt Romney says he praises rival President Obama for ordering the raid that killed al-Qaeda leader Osama bin Laden, but adds that the United States "can't kill our way out of this mess" of religious extremism.
Romney opened Monday's third and final presidential debate by criticizing Obama's policies toward Islamic extremism. He says that Obama missed an opportunity during the Arab Spring and says that Obama has not done enough to block Iran from building a nuclear weapon.
Obama says Romney has not been in a position to execute foreign policy, but adds that his positions to this point have "been all over the map." Romney says his strategy "is pretty straight forward: go after the bad guys."
