This is not a question a serious presidential candidate should be asking. 

A stunning revelation on Morning Joe this morning. During an interview with former NSA director Michael Hayden, Joe Scarborough unleashed a frightening nugget of information. He quoted an unidentified foreign policy expert who told him that during a one-hour briefing, Donald asked him three times: If we have nuclear weapons, why can’t we use them?

Hayden, in response to Scarborough asking about the time frame between a decision and the actual launching of nuclear missiles: “The system is designed for speed and decisiveness. It’s not designed to debate the decision.”
