The Republican vice presidential candidate, Representative Paul Ryan, says Americans are watching the “absolute unraveling” of the Obama administration at a time when “problems are growing abroad but jobs aren't growing at home.”

In a nationally televised debate at a small college in Kentucky, Ryan and U.S. Vice President Joe Biden opposed each other's policy toward Afghanistan, with Biden declaring that U.S. troops will leave Afghanistan in 2014 and Ryan taking a more circumstantial approach to withdrawal.

“We don't want to broadcast to our enemies, 'Put a date on your calendar. Wait us out and then come back.'”

On Syria, Biden praised the Obama adminstration's careful work with America's allies in pressuring Syrian President Bashar al-Assad to step down.

“We are doing it exactly like we need to do to identify those forces who, in fact, will provide for a stable government and not cause a regional Sunni-Shia (Shi'ite) war when Bashar Assad falls.”

Ryan said it has been over a year since international pressure mounted and President Barack Obama said the Syrian president should go. He said the Obama administration should have “had a better plan in place” that “more easily identified” Syrian allies, but instead allowed tens of thousands to die in the conflict and more foreign fighters to “spill into” the country.

When discussing the U.S. financial crisis, Biden asked Republicans in Congress, including Representative Ryan, to “get out of the way” and let the Obama administration fix the economy.

Biden blamed Republicans for the country's economic recession.

“They talk about this great recession that fell out of the sky, like, 'Oh my goodness, where did it come from?' It came from this man voting to put two wars on a credit card.”

Ryan fired back by asserting that President Barack Obama and Congressional Democrats came into office in 2008 with “one-party control” that gave them the ability to do “everything of their choosing.” He said that the administration told Americans that if the stimulus was passed, the economy would grow at four percent, but it is only growing at 1.3 percent.

On Libya, Biden called last month's fatal attack against the U.S. ambassador to Libya “a tragedy,” promising that whatever “mistakes” were made “will not be made again.”

Ryan slammed the Obama administration for not providing enough security in Benghazi and for taking “two weeks to acknowledge that this was a terrorist attack.”

“Our ambassador in Paris has a marine detachment guarding him. Shouldn't we have a marine detachment guarding our ambassador in Benghazi, a place where we knew that there was an al-Qaida cell with arms?”

The vice president argued that President Barack Obama was not told that the consulate wanted more security.

On Iran, Ryan said the Islamic Republic has become “brazen” because the Obama administration has “no credibility” on the issue of Iran's nuclear program. Biden countered this claim, asserting that the U.S. has placed “the most crippling sanctions in the history of sanctions” on Iran.

The debate late Thursday comes as Republican presidential nominee Mitt Romney is gaining momentum in voter opinion polls after his strong performance in last week's debate against the Democratic incumbent, President Obama.

The 69-year-old Biden is widely regarded as an experienced debater and skilled politician, based on his 36 years in the Senate before becoming vice president in 2009. Ryan, a 42-year-old congressman from Wisconsin, is considered a rising star among conservative Republicans.

The presidential contenders were back on the campaign trail Thursday, with Mr. Obama rallying supporters in Florida. Mr. Romney addressed supporters in North Carolina before plans to crisscross the battleground states of Virginia and Ohio on Friday. Those four states hold a combined 75 of the 270 electoral votes needed to win the November 6 election.
