SUBJECT: Telephone Conversation - Don Hornig (18 September)

His main purpose was to nick me in the sides for Humphrey which I re-
fused to do for the time being waiting to hear some better statements
about his policy on Vietnam. Hornig did bring up Humprey's interest
in arms control which I, of course, acknowledge as an important con-
sideration.

I brought up with Hornig the criticism of Rusk's view of exchange pro-
grams. Hornig dismissed this as a trivial incident that Rusk was im-
portant to save the real guts of the exchange programs. In fact, he
said that he had been criticized at the recent meeting in Vienna of
the Physicists for why the United States had not expressed itself
vehemently in reaction to the Czech invasion. I did try to point out
that a message from the Czechs and, perhaps, also from the Soviet
scientists might undercut the attack now being mounted on Senate rati-
fication of the nonproliferation treaty. He missed the point about
this for quite awhile then dwelt on the likelihood that any statement
on the subject from Soviet scientists would be contraproductive. He
eventually did get the point about looking for some reading on the
subject from the Czech government of some representatives of the

Czech liberal thought. I did spend enough time on this question to be
sure that he did understand this final point, and I have the impression
that he will try to follow it up in some way.
