Unconditional surrender is a specific thing. It is not a mood or a press line. It is a document signed on a deck, with no terms, by a party that has run out of them. The defeated keep nothing they are not handed back out of pity. By that standard, exactly one government signed an unconditional surrender this week, and it was not the one in Tehran.

The President says otherwise. Asked by a reporter why the memorandum he digitally signed in Versailles looked nothing like a capitulation, he considered the question and concluded that, well, really, it probably is one. This is the foundational technique of the entire enterprise: a retreat, narrated with sufficient confidence, becomes an advance. He did not surrender. He merely signed the only kind of document a surrendering party signs, and then renamed it.
