Could be.
There is an old line that I suspect Melania connects to. Comes out of Montenegro. Maternal line. Connects to many French and Russian royal lines. The aunt/cousin from the movie "Anastasia" is from that same line that was married into the Romanovs.
It will take too long to recount my own spoopy story, but I knew a Montenegrin lady who spoke with a very high class manner. Spoke as many languages as Melania. Of note were Russian, English, and Japanese. Went by a screen name of "mokusei" and enjoyed the symbolism of masks.
Mokusei is a book about a Danish man in Japan and his discussions with another European about why Japan was so interesting.
She gave me a story about how she lived in Japan. Her father was doing something there. When the war began to heat up from Bosnia to Kosovo, he decided to return. Apparently held some rank in the Serbian military. She later claimed (under another account) to have intercepts of U.S. military comms from that period.
We all know how Madeline Albright handled that war, and there are people still under (potentially false) war crimes charges. It was after that war that the Pentagon started doing a serious auditing of its expenses - the plane that hit the Pentagon did damage to that audit investigation (or an excuse for it).
Operation Cyclone.
I call her "Ninja-Hime" - as to how it was I came to know this person… I'll leave that one for after the cabal is taken down and after my own potential ties to that line are settled one way or the other. My dad was kind if like Q, and my family name and meaning point to the cultural nexus of all Slavs.
