The neither confirm nor deny policy1990

"The aim of this study is to provide an understanding of the true purposes of, and use of this policy. Records for the 1983 to 1985 period of port calls by United States nuclear capable warships to supposedly nuclear weapons free ports in the Scandinavian region and in Japan and New Zealand together with some significant related events are analysed, and violations of the supposedly inviolable NCND policy considered. From these analyses and other evidence it is claimed that the policy is clearly shown to be used to allow the covert unhindered movement of nuclear weapons regardless of the non-nuclear policies of many countries. The policy is oppressive in its operation, obstructs arms control, and is obsolete. Proposals are presented for its elimination"-- Abstract.
