Buchanan was refused entry after the US refused to declare the presence or absence of nuclear weapons, and a year after the US suspended its treaty obligations to New Zealand. This law effectively made the entire country a nuclear-free zone. Despite the ANZUS split, Secretary of State George P. Shultz maintained that the ANZUS structure was still in place, should NZ decide in the future to reverse its anti-nuclear policy and return to a fully operational defence relationship with the US. President Reagan also maintained in NSDD 193 (National Security Decision Directive) that New Zealand still remained a "friend, but not an ally".

The United States provided only limited logistical support but the provided air defence for the initial entry operation. The operation was taken over by the United Nations.
