If I'm correct, the 'Football' is an electronic device; no matter the sophisticated redundancies involved with activation. The Loons on the Extreme Left and Extreme Right-- not to mention our enemy states-- are populated with antisocial 160 IQs.  

Without question, if it's a programmable widget it can be hacked.  That is more plausible than any Trump/Milley conspiracy.  (I'm assuming Milley has the codes and a key, too).

It wouldn't surprise me if Anderson Cooper thinks Ivanka has the second key; and, the CODE is '!!OLIVe GARDeN."

IMPORTANT: The code requires at least one special character, two capitalized letters and one or more non-capitalized letters.  If armed, you will hear one 'BING.' If you hear two BINGS, drop the thing and run like hell.
