Its not about what the message says exactly(because its for the military), its about why the Morse code was put there in the first place.

Julain Assange was in "Quotation Marks" as in the person that made that tweet was from the Navy and was standing right next to him(JA) when he posted it.
JA was in the USA testifying from around Christmas of 2017 until about 2 weeks before he was arrested. the DOJ plane that was seen headed towards the Ecuadoran embassy was not picking up, they where dropping JA off.
If they hide RBG from the media surly JA would be even easier. I mean nobody seen him or his cat for nearly a year
