With a nuclear nonproliferation treaty under consideration in Washington, INR considered which countries were likely to sign on and why or why not. INR analysts, mistakenly as it turned out, believed it unlikely that the Soviet Union would be a co-sponsor of a treaty in part because of the “international climate” and also because Moscow and Washington differed on whether a treaty would recognize a “group capability.”

The Swedish government rejected Supreme Commander Torsten Rapp’s proposals to fund a nuclear weapons program. This INR report from March 1967 on proposed cuts in defense spending suggested that the possibility that Sweden would acquire nuclear weapons had grown even more remote.

In 1966, Sweden's Supreme Commander of the Armed Forces. Torsten Rapp, sought funds to support planning to produce nuclear weapons.
