I have seen no evidence that would indicate to me that the Soviet Union considered that it had an interest in the removal of President Kennedy or that it was in any way involved in the removal of President Kennedy.

I have not seen or heard of any scrap of evidence indicating that the Soviet Union had any desire to eliminate President Kennedy nor in any way participated in any such event.
Now, standing back and trying to look at that question objectively despite the ideological differences between our two great systems, I can't see how it could be to the interest of the Soviet Union to make any such effort.

I do think that the Soviet Union, again objectively considered, has an interest in the correctness of state relations. This would be .particularly true among the great powers, with which the major interests of the Soviet Union are directly engaged.

I think that although there are grave differences between the Communist world and the free world, between the Soviet Union and other major powers, that even from their point of view there needs to be some shape and form to international relations, that it is not in their interest to have this world structure dissolve into complete anarchy, that great states and particularly nuclear powers have to be in a position to deal with each other, to transact business with each other, to try to meet problems with each other, and that requires the maintenance of correct relations and access to the leadership on all sides.

I think also that although there had been grave differences between Chairman Khrushchev and President Kennedy, I think there were evidences of a certain mutual respect that had developed over some of the experiences, both good and bad, through which these two men had lived.

I think both of them were aware of the fact that any Chairman of the Soviet Union, and any President of the United States, necessarily bear somewhat special responsibility for the general peace of the world. Indeed without exaggeration, one could almost say the existence of the northern hemisphere in this nuclear age.
