Sen. Lindsey Graham (R., S.C.) isn’t happy about the short shrift foreign policy is getting in the GOP primary.

“I want our presidential candidates to talk about foreign policy,” he said on Fox News Sunday this morning. “What would you do with Gitmo? Would you use it? Would you let the CIA interrogate prisoners? What would you do in Afghanistan? Would you pull all of the troops out by September of next year, compromising the second fighting season? What would you do with Iran if they tried to kill an ambassador here on U.S. soil? What is your policy to stop the Iranians from getting a nuclear weapon?”

Calling the national security decisions President Obama has made “strategically unsound,” Graham called on Republicans to “challenge” the President, arguing that in addition to the jobs crisis, the United States also has a “national security problem that’s growing by the day.” The Republican candidates, Graham says, have not been “robust enough” in their criticisms against the President on that score.

“To the Republican party: national security matters, step up on it,” Graham warned.
