So the US has agreed to send a ship to the RNZN 75th anniversary celebrations in November. That means that it has accepted New Zealand’s non-nuclear policy and will send a ship that is neither nuclear armed or propelled. It may have taken 33 years for it to finally loosen up on its “neither confirm or deny” policy when it comes to nukes on board, but the US realises that the geopolitical and strategic environment in which that policy was adopted is long gone and has been replaced by another in which continuing to adhere to it is a matter of hubris that is both churlish and counterproductive. Given the pressing realities of Chinese strategic competition in the Western Pacific and elsewhere, the US needs to consolidate its alliance commitments in the region. If acknowledging New Zealand’s non-nuclear stance is one way of doing so, than any loss of face is well worth it.

Pundits on the NZ Left and Right have claimed that NZ has “won” in its dispute with the US and that it is a great “victory” for the anti-nuclear movement that took to the waters of the Waitemata Harbour three decades ago. Quite frankly, I find the crowing about victory to be infantile because there were many other factors at play and decisions such as this are not a simple matter of win or lose. Moreover, with the Wellington and Washington agreements and RNZN participation in the annual US-led RIMPAC naval exercises, the bilateral military relationship between New Zealand and the US is pretty much back to first-tier partner status regardless of the symbolic stand-off about nukes. Add to that the fact that US nuclear submarines regularly patrol around (and some suggest in) NZ territorial waters, and the reality is that NZ’s non-nuclear status does not impede US naval operations near its shores regardless of what is said in public.

The issue of the US “relenting” is all about context. First off, the strategic environment has changed considerably. It is well known that US surface ships, with the exception of carriers, are all diesel power and as of 1991 have not carried tactical nuclear munitions. Even if resurgent, Russia no longer poses the global nuclear threat to the US that it once did, and although China has emerged as the giant’s rival in the last two decades, it still has limited capacity to project blue water force deep into the Pacific in a measure that would constitute a direct challenge to US maritime interests. However, the Chinese are working hard to address that imbalance, evident in their land reclamation projects in the South China Sea and their overtures to South Pacific island states with regard to naval port visits and fishing rights, something that the US views with concern and which in part motivates Vice President Biden’s whirlwind tour of the region this week. Likewise, the re-establishment of the Russian Pacific Fleet also signals that the era of US maritime supremacy is now subject to contestation, so the US well understands that it needs all of its military allies working off of the same page when it comes to these new challenges. Recognizing the RNZN on its anniversary is one small way of doing so.

More importantly, from the moment President Obama stepped into the Oval Office he made de-nuclearization a cornerstone of his foreign policy. The Iran nuclear deal, the increased sanctions levied on North Korea, the slowing of advanced weapons sales to Pakistan, the repeated attempts to engage in bilateral strategic ballistic missile reductions with Russia–all of these efforts were undertaken as part of Obama’s vision of a safer world. It is therefore completely logical given his commitment to a world without (or at least with lesser amounts of) nuclear weapons, that under his administration the US would relent on the issue of NZ’s non-nuclear policy. In fact, it can be argued that the Obama administration wants to highlight its agreement with the principled commitment to a non-nuclear stance by authorising a US ship visit on a ceremonial occasion with symbolic significance given that several other nuclear powers will be among the 30 odd nations sending naval vessels to the celebrations–including its new competitors.

I have publicly suggested that the US send the USS Mercy, a hospital ship home ported at Pearl Harbour. It would symbolise the humanitarian aspects of naval deployments that the RNZN claims as one of its core missions and would defuse the grounds for opposition of protesters who see US warships as imperialist death platforms. Surprisingly, this suggestion has been ridiculed by some (most on the Right) who say that a ship without guns is not “exciting” and is not a real naval vessel. Given that navies around the world have tenders, tankers, tugs, intelligence collection vessels and assorted other non-combat ships, it strikes me as strange that some people think that the US decision to send a navy ship is a victory for NZ and yet that victory must be confirmed with a warship visit as opposed to something with a non-combat purpose. Given that the NZDF spends much time publicising its non-combat, peacekeeping and humanitarian roles, I would have thought that a visit by a US naval vessel whose purpose was something other than kinetic operations would be perfectly suited for the occasion.

In the end the decision by the US to accept the invitation to send a ship to the RNZN anniversary celebrations was a triumph of good sense over bureaucratic intransigence within the US defense establishment, pushed as much by the president’s commitment to a nuclear weapons-free world as it is by the evolving strategic realities in the Western Pacific Rim that require the US to consolidate its military alliance commitments in the region. Some in NZ may think that it “won” and the US lost with its change of posture, but a simple glance at geopolitical realities suggests that it was not the NZ non-nuclear movement that forced the change so much as it is the influence of much broader factors in a context when haggling about nukes on board is about as relevant to modern naval warfare as is arguing about the relative merits of spinnakers and mainsails.
