In "What is Russia to Us?" here Codevilla vainly imagined Russia to be self-limited by the sobering lessons it has learned from its history:
Today, [John Quincy Adams] would be confident that Russia realizes it cannot control
Ukraine except for its Russian part, or the Baltics, never mind the
states of Eastern Europe. ...
Adams would not hide the fact that U.S. policy, implemented by ordinary diplomacy, is to foster the Baltic States’, and especially Ukraine’s, independence. But he would know and sincerely convey to Russia that their independence depends on themselves, and that he regards it as counterproductive to try making them into American pawns or even to give the impression that they may be. He would trust in a Ukraine that had stopped longing for the borders that Stalin had fixed for it in 1927 and Khrushchev augmented in 1954, in a Ukraine retrenching into its Western identity (as, for example, by asserting its Orthodox church’s independence from Russia’s), and that is standing firmly on its own feet. He would trust in Russia’s actual acceptance of its inability ever again to control this Ukraine. This would be Adams’s Ukraine policy.
