That was my thought as well. Is the peace treaty/denuclearization agreement already signed? I can see Trump wanting that hugely important deal signed, sealed and ready to announce when appropriate before he unleashes the public face of The Storm.
I remember some planefags noticing a.gov flight from Europe arriving at Andrews AFB around the time that Q posted the painting of Washington crossing the Delaware which, not coincidentally, commemorated a surprise attack against the Hessian mercenaries at Trenton that began the night of December 25-26, 1776. Speculation at the time of the posts was that JA had been exfiltrated from the Ecuadorian embassy and flown to the US. The references to [kill_rogue] and Twitter FW_ were interpreted to mean that JA's old Twitter account was being replaced, possibly to ensure security, and that JA was told that the floor was his, meaning tweet as you see fit.
