Donald Trump has said that in order to defeat ISIS, he’d kill their wives, mothers and children. Now he’s saying he won’t rule out using nuclear weapons against the terror group, which any sentient human knows would involve murdering countless women and children.

Unpredictability. That’s what Donald Trump has promised as part of how he would combat ISIS as president. He has also proposed killing the families — wives, mothers, and children included — of ISIS fighters and other terrorists. When asked during an interview with NBC’s Today on Thursday whether he’d use nuclear weapons in the fight, Trump said he wouldn’t rule it out:

TRUMP: I don’t want to rule out anything. I will be the last to use nuclear weapons. It’s a horror to use nuclear weapons. The power of weaponry today is the single greatest problem that our world has. … I will be the last to use it. I will not be a happy trigger like some people might be. I will be the last. But, I will never, ever rule it out.

This”unpredictability” is perhaps what led Good Morning America host George Stephanopoulos to ask Trump this week: “How do you convince people that they can trust you with the nuclear codes?”

And it’s what has the entire world in a state of apprehension.
