“The Reagan Diary” for those interested:
First mention of INF is a short note:
Monday, September 13 
National Security planning group meeting on INF.
Thursday, March 10 
An N.S.P.G. meeting on I.N.F. and Lebanon. I’m of the mind we should tell Nitze [Advisor Paul Nitze, later Sec. of the Navy] to offer an interim missile reduction plan to the Soviets while still claiming zero is our ultimate goal.
Thursday, August 11 
I’m packed & ready to head west [the ranch] tomorrow. First will have a big meeting on our I.N.F. strategy. Some want us to make some new movements just for the P.R. of it. I think to h–l with that—let’s settle on the bottom line & fight it out.
Tuesday, October 13 
NSC—discussion of INF Treaty as it appears to be & question as to whether we can get it ratified. The Dem’s in the Sen. are feeling their oats.
Friday, October 30 
Shevardnadzehad brought me a letter from Gorbachev. It was statesmanlike & indicate a real desire for us to work out any differences. The outcome of the letter & meetings was a summit to start here on Dec. 7. Purpose to sign INF Agreement and set in motion START Treaty to reduce ICBM’s by 50% to finalize that at a summit in Moscow next Spring.
Thursday, December 3
Then it was NSC time. A report on travel expenses of Soviet summiters. They’ve demanded 50 we’ve said 20. But at Madison hotel they empty the mini-bars in their rooms into their suitcases every morning in addition to running up big bar bills—all of which we have to pay. The St. Dept. has already had to ask Congress for a supplemental appropriation.
Monday, December 7
Colin [Gen. Colin Powell] warned that Gorbachev may suggest a zero-zero agreement on short range tactical nuclear weapons—that can only happen after we agree to parity on conventional weapons.
We should get together on banning Chemical weapons but that’s a tough one to verify.
