Because much of what Donald Trump says is unhinged and histrionic, it’s tempting to dismiss all of it as bunk.

And yet the former and perhaps future president has a populist knack for sounding alarms that resonate with the zeitgeist — for example, with growing anxiety about World War III and nuclear Armageddon.

"We're a failing nation,” Trump ranted during his debate against Vice President Kamala Harris in one particularly meandering answer (the one that also recycled urban myths about immigrants eating cats). "And what, what’s going on here, you're going to end up in World War III, just to go into another subject.” He brought it up twice more. "We’re going to end up in a Third World War,” he closed. "And it will be a war like no other because of nuclear weapons.”
