You're wrong Malg. Simple as that.
People have shared links, you call them bollocks because it used American spelling (in an American outlet!) and yet you tell others to grow up. Laughable really.
Find a link that doesn't say what Bob quotes then:
'Only the President can direct the use of nuclear weapons by U.S. armed forces, including the
Single Integrated Operational Plan (SIOP). While the President does have unilateral authority as commander-in-chief to order that nuclear weapons be used for any reason at any time, the actual procedures and technical systems in place for authorizing the execution of a launch order requires a secondary confirmation under a
two-man rule, as the President's order is subject to secondary confirmation by the Secretary of Defense. If the Secretary of Defense does not concur, then the President may in his sole discretion fire the Secretary. The Secretary of Defense has legal authority to approve the order, but cannot veto it.

Explain to us why it's bollocks rather than it just being a hunch.
I await you coming back and either showing why everyone other than you are wrong OR popping back for some mea culpa, I hear it's cathartic anyway.
