A 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.
