At least he did respond after being asked twice. I remember reading about an incident where the US military had a clear shot at a terrorist target but needed the OK from the President, who was Bill Clinton. Clinton was watching something on TV (like a golf tournament) and refused to break away from that and give his OK—in fact, chewed out the aide who tried to get him to take action—and the chance to hit the target was lost.
I doubt that the command even came from FUBO ... it probably came from staff ...
That terrorist target was Osama bin Laden, and Clinton was on a golf course at the time. And yes, he finally chewed out the aide who continued to communicate the request for clearance to fire.
