Speaking with “60 Minutes” correspondent Bill Whitaker, Harris was asked which nation she considers “to be our greatest adversary.”
“I think there’s an obvious one in mind, which is Iran,” Harris replied. “Iran has American blood on their hands. This attack on Israel, 200 ballistic missiles.”
“What we need to do to ensure that Iran never achieves the ability to be a nuclear power, that is one of my highest priorities,” she added.
Whitaker followed up, asking, “If Iran is building a nuclear weapon, would you take military action?”
“I’m not going to talk about hypotheticals at this moment,” said the vice president.
So Iran building nuclear weapons was the greatest adversary and also a hypothetical. 
Libs hate the very idea of bombing Iran now though.
