DES MOINES, Iowa (AP) -- The specter of U.S. military action against Syria and further intervention in the Muslim world is generating troubled and conflicting emotions throughout America.
People cite misgivings about their country's role as "world policeman." They express moral outrage at atrocities in a faraway nation, tempered by dismay about trying to decide who's good and who's bad in a sectarian slaughter. There's a deep ambivalence about how to use American military power for good without committing the United States to another intractable war.
Those sentiments are reflected in a series of interviews conducted Friday by The Associated Press across the country and borne out in recent polling.
In town after town, Americans weary of war after a dozen years of it are expressing unease, concern, fear and often resignation.
Some adamantly oppose any U.S. action against Syrian President Bashar Assad's government, even though the Obama administration says he used chemical weapons to kill 1,429 people, including more than 400 children. Obama said Saturday he would seek congressional approval before launching any strike.
With Navy ships in the Mediterranean Sea ready to strike, Obama said he had decided the United States should take military action, but also determined "our country will be better off" if Congress renders its own opinion.
At the same time, he challenged lawmakers to consider "what message will we send to a dictator" if he is allowed to killed hundreds of children with chemical weapons without suffering any retaliation.
Lawmakers will return to session on Sept. 9.
Most are struggling to sort out conflicting hopes and anxieties. Painful lessons from Vietnam and Iraq color the conversations. Pride in America's strength and morality often seem pitted against fears of arrogance that can lead to conflicts much easier to start than to finish.
"I think he has to do something," Ralph Whitney of Groton, Conn., said of Obama, even if it means "stirring up a hornet's nest."
Opinion polls quantify the serious reservations.
An NBC News survey suggests that the Assad government's alleged use of chemical weapons has not persuaded more people in the U.S. to support military intervention. Half of those surveyed said the U.S. should not take military action, while 42 percent said the U.S. should.
Only 1 in 5 said military action is in the U.S. national interest.
The poll was conducted Wednesday and Thursday, before the administration's release Friday of an unclassified intelligence assessment that cited "high confidence" that the Syrian government carried out the attack.
A Washington Post-ABC News poll from December showed 63 percent in favor of U.S. military involvement if the Syrian government used chemical weapons against its people.
The NBC poll found scant support for arming Syrian rebels. About one-fourth of those questioned favor U.S. military action to help stop the killing of Syrian civilians, while just 6 percent prefer arming the rebels.
Americans with firsthand knowledge of Syrian refugees' plight talked in Des Moines about their wariness of U.S. military intervention.
"The pain and the despair people have experienced, and the loss of life, it's created a situation where people don't even know who they are anymore," Kate Altmaier, a 30-year-old administrative assistant, said in between sips of coffee outside a cafe.
Altmaier had just returned from the Mideast. In Lebanon, she saw the struggles of those refugees.
Anyone who thinks America's proper response is easy or obvious, she said, is misguided.
"Fighting evil with more darkness," said Altmaier, a self-described born-again Christian, is not the answer. "If someone has a good answer, I'll say they don't understand it. Even people who know a lot about it and have spent so much time there, it's a spider web."
Nearby, Elizabeth Jack was rocking her 5-month-old after the weekly story hour at the city's downtown public library. A family of Syrian immigrants lives in her neighborhood, she said, and the kids in the two households play together.
The Syrian parents fear for relatives still in the Middle East. "I know they are worried, and want someone to help," Jack said.
Despite her sympathies, Jack opposes a U.S. strike.
"We're stretched so thin," she said. "We are policing the world."
She said her views sometimes create awkwardness with her Syrian neighbors.
Jack said she feels helpless to change America's military role in the region. "I do feel like it's just the way it's going to be," she said.
Jimmy Tynes, 64, of Hattiesburg, Miss., said his initial thought on airstrikes against Syria was, "I'm against it. I just don't know what we'd be doing over there."
