Mattis pretty much knows what he is doing.
DJT, not so much (in fact he hasn't a clue). But, hey, he has said that he knows more than our Generals AND his preppy school was tougher than what our Armed Forces endure! (see what I mean?)
Mattis knows what he is doing when it comes to DEFENSE... OTOH: DJT hasn't a clue.
DJT's THEME SONG:
~ I know, you know, they're busy gathering proof. ~
~ Embrace my deceptions - learn how to bend, ~
~ Or these investigations will surely mean my end. ~
(loosely adapted from the TV Show "Psych" Lyrics, performed by "The Friendly Indians")
