What do Gen Z and millennials consider to be the number one national security threat?

According to Kayleigh McEnany, both Gen Z and millennials have identified the national debt as the number one national security threat they face. This concern has become particularly popular among younger generations who are worried about fiscal responsibility and government spending. McEnany notes that while figures like Elon Musk and platforms like X (formerly Twitter) are very popular with Gen Z, their underlying concern about the national debt reflects a growing awareness of economic challenges. She also suggests that progressive politicians are either unwilling or unable to adequately address this concern that resonates strongly with younger Americans.
