An Anxious Europe Ponders Nuclear Weapons

After comments made by the US presidential candidate, Donald Trump, some Europeans are considering the possibility of acquiring nuclear weapons. They should think again. On 10 February, former United States President Donald Trump recounted a conversation with an unnamed European counterpart in which he stated that he “would not protect” them from a possible Russian attack because they failed to allocate two percent of their gross domestic product to defence, and thus fell short of North Atlantic Treaty Organization (NATO) spending targets. Such delinquency would lead Trump to “encourage [Russia] to do whatever the hell they want.” Given Trump is the probable Republican candidate at the election in November, and currently polling ahead of incumbent President Joe Biden, these comments have triggered concern among European leaders, including German Foreign Minister Annalena Baerbock, Polish Defence Minister Wladyslaw Kosiniak-Kamysz, as well as NATO Secretary General Jens Stoltenberg. These concerns were exacerbated on 9 February when Danish Defence Minister Troels Lund Poulsen warned that Russia might militarily challenge NATO’s mutual defence article within the next three to five years, considering “new knowledge.” Some are now calling for the expedited integration of European defence capabilities to the point of acquiring nuclear weapons. This conversation was initiated by European Union (EU) parliamentary vice president Katarina Barley who perceives a joint nuclear deterrent as part of Europe’s path toward to an eventual joint EU army. Her fellow social democrat, former German foreign minister Sigmar Gabriel concurs, as does German Finance Minister Christian Lindner. However, others – such as chancellor Olaf Scholz, Defence Minister Boris Pistorius, or Marie-Agnes Strack-Zimmermann, who chairs Germany’s parliamentary defence committee – deem a European nuclear option “unrealistic.” According to political scientist Karl-Heinz Kamp, “debate about European nuclear weapons is a very German debate.” Nonetheless, non-Germans have also chimed in, including the chair of the EU Military Committee Robert Brieger – who argues in favour of European nuclear weapons – and Stoltenberg, who opposes them. Until recently, discussion of a European nuclear deterrent was unthinkable. Current debate fluctuates between proposals for joint EU nuclear procurement, merging existing capabilities, and individual European states acquiring nuclear weapons. Indeed, there are many barriers to all of these options, including the Nuclear Non-Proliferation Treaty (NPT), and the ongoing stationing of American nuclear warheads on European soil. One suggestion might propose that the two existing European nuclear powers, namely the United Kingdom and France, could increase their stockpiles and integrate them into a joint framework. However, this is also unrealistic as the cost of these two powers expanding their stockpile would be exorbitant. For instance, Britain is already projected to spend 34 percent of its military budget on maintaining its existing nuclear arsenal. Moreover, it is unlikely that the UK would participate in an EU nuclear weapons program post-Brexit. European states would do well to consider Australia’s pursuit of nuclear-powered submarines through the AUKUS agreement to inform their own ongoing debate. While these submarines will not carry nuclear warheads, regional powers such as Indonesia did question AUKUS’ legitimacy, considering Australia’s commitment to non-proliferation. Certainly, the outright pursuit of nuclear warheads by the EU would be legitimately challenged in the same way. To acquire nuclear weapons, European states would have to withdraw from the NPT which would, no doubt, undermine the international rules-based order that they wish to preserve. Furthermore, it would be hypocritical of Europe to insist on non-proliferation, for instance toward Iran through the Joint Comprehensive Plan of Action (JPCOA) or other states which might wish to acquire nuclear weapons, such as Saudi Arabia or South Korea, but then become a proliferator itself. This would set a dangerous precedent, potentially perceived as a “go ahead” by other states who wish to acquire nuclear weapons. Similarly, it is questionable whether the US would tolerate nuclear proliferation in Europe. Certainly, the US has the means to prevent the pursuit of nuclear weapons, as seen in 2009 and 2010 when it allegedly employed the Stuxnet computer virus to sabotage Iranian enrichment centrifuges. Even if the US were to abstain from sabotaging European efforts, it would nonetheless constitute a rupture in the transatlantic alliance. That Trump would only be president for four years, were he to return to the White House, it is short-sighted to sacrifice the important postwar alliance structure which has hitherto guaranteed peace in Europe, in favour of a potentially calamitous undertaking. Furthermore, it is questionable whether the EU as a whole, with its slow-moving bureaucracy, could acquire nuclear weapons in a timely manner. This question would likewise apply if individual European states were to pursue independent nuclear capabilities, as none appear in a position to do so with expediency. While current discussions about European nuclear weapons emphasise the need to deter Russia, the reality is that such weapons cannot be acquired overnight. Their acquisition would likely take years, if not decades, and Europe must deter aggressors today. A fruitful caveat of these debates has been the suggestion to integrate European arms procurement. As the second anniversary of Russian’s invasion of Ukraine passes, Armin Papperger, the chief executive of Rheinmetall – one of Europe’s biggest defence contractors – warned that the continent requires at least a decade to be able to defend itself from a sophisticated aggressor. Presently, European governments procure arms individually through their respective national bureaucracies. A more efficient mechanism would be an integrated, EU-wide procurement processes, for instance through the Permanent Structured Cooperation (PESCO). Ultimately, such procurement integration could pave the way for a joint European defence force. US presidents have rightfully criticised Europe for not abiding by the two percent rule, as President Barack Obama did. However, European states have drastically improved in this regard. While only four NATO states met the two percent target in 2017, today eleven do, and another 18 members are inching closer to it. Next month, EU Commission President Ursula von der Leyen plans to present a new European defence industrial strategy that aims to increase defence spending, improve interoperability, and establish joint procurement of conventional arms. This shows that Europe can adapt – when the political will to do so exists. Ultimately, Trump’s comments, and the prospect of his return to the presidency, have triggered an overdue conversation in Europe. While a possible second Trump administration would be comparatively short-lived, Europe must consider how it plans to defend itself without the American nuclear umbrella. On the road toward greater integration, collective defence will be of paramount importance. However, European states, largely embodied by the EU, should shy away from a precarious nuclear option. Rather, its resources should focus on the procurement of conventional arms and ammunition, and not on expensive Cold War era weaponry.
