“I’m just going to be honest here,” Graham said. “I’m not that informed on national security.”

“I’m not a polished politician up here,” she said. “National security is not my thing, not my area of expertise. But I do support the military.”

Norman, however, used the question to champion Trump’s policy of “peace through strength,” noting that Taiwan is an ally of the U.S. and collaborates in the chip manufacturing industry.

“What the president is doing right is he’s enabling Taiwan to defend themselves against China, but it’s peace through strength that he’s showing with Iran that China, Russia, others are looking at it so that they don’t want to deal with America, and that’s why they haven’t attacked Taiwan,” Norman said.

National security has proven to be a weak point for Graham, particularly as she seeks to succeed her brother, a well-known foreign policy and national security hawk who vocally supported Taiwan. On other areas of national security and defense policy, Graham stuck by her brother’s views, saying she would support Trump’s policies.

When pressed about the Iran war and Tehran and Washington’s failed ceasefire agreement, Graham delivered a similar line.

“I fully trust President Trump when it comes to the war in Iran,” Graham said. “47 years this has been going on. Iran is the weakest they have been in 47 years. The one thing that concerns me is we cannot let them get a nuclear weapon, so I trust President Trump and everything he’s doing. I think he’s got this, and I trust him on it.”

Norman, however, slightly checked the president on his Iran war approach and said Americans need to be better informed by Trump about what is going on in the Middle East.

“Win looks like — I mean, he took them out militarily as far as getting a nuclear weapon, where you had, you know, Obama paying cash bribes in the middle of the night, so [Trump] did the job to take them out,” Norman said. “They were a severe threat, and he had the courage to do that. Now, I think that we’ve got to end it. … He’s got to tell the American people what’s it going to take. If the Strait of Hormuz are still dominated by a country that’s supposed to be decimated, we got to have some understanding on that because I’m not for endless wars. You win them and you get out. And so I think once he explains that as what’s going to have to be done.”

DOES ANYONE WANT TO WIN THE MIDTERM ELECTIONS?

On defense policy, Graham also noted the importance of approving defense spending, hitting her opponent for previously voting against a defense spending bill. Norman clarified that he had only voted against the unspecified bill in question because he saw a better deal, noting his role as a businessman.

Graham and Norman will face off in a Republican primary runoff on Aug. 25.
