Can anyone imagine a committee meeting in time of a nuclear attack?
These people are nucking futz!
They got their guy in there. Deal with it.
The launch order gets relayed through the Secretary of Defense, there's no button in the football briefcase that goes directly to the missile silos.
If there was an incoming attack, the chain of command would already be primed to receive a launch order. If Biden, out of the blue, decided to tell SecDef to nuke Belgium, then the chain of command, starting at SecDef, would have the opportunity to say "wait a minute", and have an emergency 25th Amendment chat with the VP.
“... relinquish full control over the country’s nuclear weapons in favor of a committee approach …”
“A committee is an organism with 6 or more arms, 6 or more legs, 3 or more heads and no brain.” - Robert A. Heinlein
