U.S. combat troops won't be returning to Iraq.

That option is being ruled out by President Barack Obama -- but he says he's considering a range of other options for dealing with the violent Islamic insurgency there.

Gulf War veteran Dominic Van Horn said the U.S. shouldn’t be the police of the world.

“I'd like to see us stay out of the conflict, we can't change everything they done, that's their way of life,” he said.

The last U.S. troops withdrew from Iraq in 2011 after more than eight years of war.
Obama says Iraq's government must make a sincere effort to address sectarian differences, or else U.S. military help won't succeed in curbing the insurgency there.

He says, "We can't do it for them."

Obama says the risk posed by terrorists in Iraq could eventually pose a threat to U.S. interests, too.
