Garthoff:
The fact that the United
States had already successfully tested a MIRV at that time, and the Soviet Union hadn't even
begun its testing program meant that there was a real question on the Soviet side, and... would
have been a certain risk, or sacrifice on their part, to have frozen a situation in which we had
tested MIRVs, even if we agreed not to deploy them; and where they would not be able to catch up
with...us in testing. But they also understood that... the ban on testing was the real handle on
verifying such a ban, and that although the Soviet Union was behind us at that time, that very
fact made it possible for the United States to consider a ban that would be verified by a limit
on testing. And and when I've... said that senior Soviet officials told me they believed that
their government would have agreed to a test ban, it's with an understanding that they would
have had the would have had to accept that continuing situation in which the United States had
tested a MIRV and they had not; but the, they still believed that the effects of a, of a ban
would justify it. Now... Dr. Kissinger would, I don't question that he believes that the Soviet
leadership was not ready to agree to a MIRV ban, but at the time, at any rate, he wasn't sure
enough to let us try. When the delegation requested authority, not to withdraw the on-site
inspection or to withdraw anything else from our proposal, but just to add to it a ban on
production of MIRVs, we were denied authority by Washington to make that proposal. And yet
without that element, our proposal was on the face of it unacceptable to the Soviets, because we
had tested a MIRV, we could produce one, and if we insisted on keeping open a loophole that
would permit us to continue actually manufacturing and producing MIRVs, and only barred us from
actually putting them on the missiles we could build up thousands and thousands of MIRVs quite
legally, whereas they couldn't even test in order to develop one. So, our proposal was
absolutely unsatisfactory without that additional proviso, and the White House would not let us
make a proposal to test out whether the Soviets were interested or not.
