During the whole Trump tenure, I have seen a bunch of what I would call discrete to very obvious Q hints and references. The most obvious has gotta be a rally speech where he kept talking about the local farmers growing cucumbers. The first time he said it was like 'cu-cumber'.. and then 'cuuuuuuuu-cumber' and then... 'we really love our cuuuuuuuuuuuuuuuuu-cumbers.' Anyway.. that was directly from him and that one stuck with me.

What other ones would you consider obvious?

“The reason that the American Navy does so well in wartime is that war is chaos, and the Americans practice chaos on a daily basis.”

― Karl Dönitz

A serious problem in planning against American doctrine is that the Americans do not read their manuals, nor do they feel any obligation to follow their doctrine

And then there's Greene, "Washington's general" and a favorite son of Rhode Island. (A moment of silence shall be observed.) It's fashionable to speak of "hybrid warfare" as though it's something new and innovative, but in fact using conventional forces in concert with irregulars is a method as old as war itself. Greene raised hybrid combat to a high art during the Southern campaign of 1780-1781, working with the likes of "Swamp Fox" Francis Marion and Thomas Sumter to divide, harry, and outrun Lord Cornwallis' crack army. Greene cheerfully conceded that no general ran away more often than he — but that he ran like a crab that could scuttle in any direction, toward the enemy as well as fleeing from him. And it worked.
