1986 — In January 1986, following the rift between New Zealand and the USA in respect of the ANZUS security arrangements Prime Minister Tom Davis declared the Cook Islands a neutral country, because he considered that New Zealand (which has control over the islands' defence and foreign policy) was no longer in a position to defend the islands. The proclamation of neutrality meant that the Cook Islands would not enter into a military relationship with any foreign power, and, in particular, would prohibit visits by US warships. Visits by US naval vessels were allowed to resume by Henry's Government.
