- In backchannel message Hakto 42 to Helsinki, Kissinger informed Smith that Nixon and Brezhnev had definitely agreed to sign the SALT agreement that night at 8 p.m. Moscow time and wrote: “Don’t be bashful about making suggestions to the other side because our impression is that they will accept anything reasonable within basic framework of agreement.” (Ibid.) In his memoirs, Smith recalled, “I wonder what would have happened if, with about seven hours left to do the editing, hold a final meeting of the delegates, and make the flight to Moscow, I had taken up this suggestion and proposed substantive changes. The expression, ‘you must be kidding’ came to mind when I read this contrived record of how Kissinger valued the delegation’s judgment.” (Doubletalk, pp. 429–430)↩
