It’s considered OPSEC, operational security.
As Commander In Chief of the US Armed Forces, he should remember “Loose lips sink ships”.
I dislike the guy as much as anyone.
He was chosen and placed for the exact reason he’s there, he’s a brain addled fool that will do what he’s told, say what he’s told to say or the minions in the background just do what they want.
He has no idea what he does and says. Very dangerous.
