Chris Turpen of Chandler, Arizona, a 45-year-old architectural project manager, also sees a U.S. responsibility to Iraq. That troubles him.
"Once you break it, you own it. But it's a war that will never be won," Turpen said.
The Islamic State fighters are fanatics who "will never go away," he said. "Don't get me wrong, we should kill every one of them, but we'll never get there. These are people that just hate America."
He thinks that Obama "had to go back in." The president has promised not to send ground troops, but Turpen would not mind if that happened.
"It's a classic example of choosing the wrong that's more right," he said.
For Hashim Al-Tawil, an artist, professor and chairman of the art history department at Henry Ford College in the Detroit suburb of Dearborn, it's difficult to see anything being done right in his homeland of Iraq.
He would like to see "an end to this group" of invading militants because they don't represent Islam, Iraqis or a good, modern form of government. But he's not sure the airstrikes will be effective.
"Chaos is all over Iraq — south, north and the center," Al-Tawil said. "What's happening today is just a small, additional sequence of that whole chaos."
He said the larger solution is for the U.S. and European nations to change their entire approach to supporting or destroying Arab regimes.
"In Iraq, there was a solid state. It was a dictatorship, that's for sure, but so is every country in that region," he said. "At least there was a country."
"Now there is no country," Al-Tawil said.
