I spent 25 years in the US Navy. For all you DING DONGS who think Joe Biden or even Donald Trump has Nuclear codes, quit smoking Crack! They change randomly every so many hours and the President DOES NOT have them on hand for reasons of "Plausible deniability". I was in the missile guidance field in the US Navy with a Top Secret clearance. All you people who think Trump will sell the codes to Putin, OR Biden to give them to China is just Ludicrous!! Also, Not 1 person can ever launch a Nuclear weapon. On a War ship it takes 3 people with different codes to do so. GROW UP people!
