I wrote «It was public doctrine in textbooks, taught at university». I very clearly intended to mean that those doctrines were shown in the open, and that they should have "rung warning bells" together with many other puzzle pieces. Nothing secret, not "documents in safes". And there have been occasions to remind analysts of them.

When the "Ruler formerly known as Mr" (the intention of a change of title was news of the past few hours) took Presidents one by one and clearly spelt out conditions - as they witness -, when doctrine was formulated in clear words and infographics available at your best bookstore (but you can probably attend a lecture), it becomes farcical to act as if Las Vegas had no signs.
