In the past year, Iraq and Syria. Possibly Palestine/Israel, Yemen, and Afghanistan, depending on your definitions. Beyond that, I know they did do the Iraq-Iran war several years back, and I think they were involved in the Lebanese civil war as well.
I don't actually consider myself a particularly knowledgeable individual when it comes to Middle Eastern history. But when people say things like this, they usually include all the marginal entries the US is involved in while ignoring all of the marginal entries other countries, presumably mostly out of ignorance. Particularly if you include "little" conflicts, you'll find that most countries spend most of their time in armed conflict with somebody, and the US isn't particularly abnormal in this regard.
