I think it might be because I misremembered and there weren't actually any Blackwater skirmishes in Syria 
. I'd like to officially play my Jeff Sessions card and state that "I did not recall".

The Trump administration is seeking to assemble an Arab force to replace the U.S. military contingent in Syria and help stabilize the northeastern part of the country after the defeat of Islamic State, U.S. officials said.
John Bolton, President Donald Trump’s new national security adviser, recently called Abbas Kamel, Egypt’s acting intelligence chief, to see if Cairo would contribute to the effort, officials said.
The initiative comes as the administration has asked Saudi Arabia, Qatar and the United Arab Emirates to contribute billions of dollars to help restore northern Syria. It wants Arab nations to send troops as well, officials said.
[...]The mission of the regional force would be to work with the local Kurdish and Arab fighters the U.S. has been supporting to ensure Islamic State cannot make a comeback and preclude Iranian-backed forces from moving into former Islamic State territory, U.S. officials say.
The idea also has caught the attention of Erik Prince, the private businessman who founded Blackwater USA and who has helped the U.A.E. and Somalia set up private security forces.
Mr. Prince said Monday that he has been informally contacted by Arab officials about the prospect of building a force in Syria but that he was waiting to see what Mr. Trump would do.
