Jon Huntsman is a long-shot for the GOP presidential nomination, but according to this piece by RCP's Scott Conroy, that's definitely going to leave a void in the adult discussion of U.S. foreign policy:
“We have a generational opportunity to clean up the map, and that’s going to require us to take a look at where we are, where we’ve deployed, and to make sure what we’re doing is consistent with American foreign policy interests and that it’s serving the taxpayers of this country,” Huntsman told reporters after his brief remarks to the few dozen Republicans on hand. “We’ve fought the good fight in Afghanistan for 10 years, and we don’t need 100,000 troops there, and we don’t need to be nation-building, and we shouldn’t. We have 50,000 troops in Germany, and I’m here to tell you: The Russians aren’t coming anymore.”...
“I think we’re going to be looking more at a Pacific-centric strategy in the 21st century,” he said. “That’s where the rising militaries are, that’s where the trade routes are going to be most prominent, so I’m by no means an isolationist; all I’m saying is, let’s deploy our interests based on a realistic look at the globe and a realistic look at our national security needs.”
