The Americans lost in Libya this week were brought back to Joint Base Andrews in Maryland on Friday, and President Barack Obama made promises that their mission would continue.

"Even as voices of suspicion and mistrust seek to divide cultures from one another, the United States of America will never retreat from the world," said Obama. "We will never stop working for the dignity and freedom that every person deserves."

That will not be easy, as anti-American demonstrations are increasing, flaring up in Israel, Yemen, Egypt and Turkey, where a crowd shouted "Damn America." Sparking it is an obscure, amateurish film mocking Islam, made in the United States.

After faulting the president earlier this week, Republican presidential nominee Mitt Romney is trying to keep a respectful tone.

"On a day like this, the sky seems to be crying as well," said Romney on Friday.

His campaign is continuing to sharply criticize the Obama administration for being inconsistent, with one aide suggesting a President Romney could have tamped down the violence.

Romney's vice Presidential pick, Wisconsin Congressman Paul Ryan, also said the president is weak-kneed on foreign policy.

"Amid all these threats and dangers, what we do not see is steady, consistent American leadership," said Ryan.

Romney knocked Obama during a closed-door Friday fundraiser in Midtown Manhattan, particularly on not planning to meet Israeli Prime Minister Benjamin Netanyahu when he visits the United States next week.

It was less weighty subjects later in the day, as Romney and his wife taped an interview where she confessed once walking in on former President George W. Bush getting a massage.

He said he admired the reality star Snooki, and wears as little as possible to bed.

As for fundraising, Romney's campaign said Friday's event brought him $4 million. The Republican trailed Obama in fundraising during the month of August.

Both campaigns are keeping an aggressive schedule to raise as much as possible before Election Day.
