Spokesperson for  Donald Trump’s front running GOP presidential campaign lashed out at his fellow Republican candidates for saber-rattling about war — inferring that they are all talk and no action — before wondering whether it does the U.S. any good to have nuclear weapons if our leaders are afraid to use them.

Appearing on The O’Reilly Factor, Trump spokesperson Katrina Pearson hammered at the other candidates while covering for her boss who, in a recent debate, was stumped when asked the country’s nuclear strike capability known as the “nuclear triad.”

“What good does it do to have a good nuclear triad if you’re afraid to use it?” Pierson asked. “And that’s where we are today and we need to fix these problems. Not just complaining and name-calling about who started this and who started that.”

Pierson’s comments stunned conservative columnist and Desert Storm veteran Kurt Schlichter, who got into a contentious argument with Pierson over her boss’s ignorance on nuclear matters.

“The point of the nuclear triad is to be afraid to use the damn thing. You want to scare the hell out of the other side,” Schlichter excitedly yelled. “And frankly, my side will be more scared if Donald Trump gets his finger on the button.”

In a previous television appearance, Pierson defended Trump’s much-criticized proposal to ban Muslims from entering the country, telling a horrified S.E. Cupp of CNN: “So what? They’re Muslim.”
