It is difficult to predict how public opinion will affect disarmament dynamics. However, it could act as a brake on disarmament progress rather than as an accelerator.

Lawrence Freedman suggests that “if popular opinion becomes animated, it is as likely to serve as a brake on disarmament progress as an accelerator.” Moreover, public opinion is unlikely to be the same in all states, creating dilemmas that are intractable or at least extremely difficult to resolve, as Zia Mian trenchantly notes. Arguments that might convince the public of one nuclear-armed state that it will gain security in a world without nuclear weapons might communicate to other states that they would lose relative power in such a world. Mian avers that “some of the potential problems over nuclear-weapon abolition that result from arguments based purely on national security and national interest” could be overcome “by broadening the frame to include normative, moral, and legal considerations” that are universal and therefore do not convey relative advantage or disadvantage. This recommendation deserves to be taken seriously. Yet, it is probably arguments from security that will ultimately overcome the braking impulses of public opinion and opposition parties contemplating decisions by their leaders to relinquish nuclear weapons.
Historically, public movements to affect nuclear weapon policies have arisen in few states, primarily in the United Kingdom, the United States, and continental Europe. Some key nuclear-armed states do not allow independent public movements. Developments since President Barack Obama’s famous April 2009 Prague speech suggest that nuclear policy does not inspire significant numbers of citizens to mobilize, even where they are free to do so. An impressive array of former officials from many states have joined the Global Zero organization, but the issue remains the province of elites. This need not impede governments from adopting policies to reduce nuclear arsenals, strengthen the nonproliferation regime, and prepare conditions conducive to the multilateral elimination of nuclear weapons. Yet if such policies were to animate popular opposition to disarmament, as Freedman speculates they might, the question is whether countervailing public opinion would be mobilized in favor of it. This is difficult to foresee especially in nuclear-armed states whose governments believe—publicly or privately—that nuclear disarmament would disadvantage them relative to their more powerful competitors.

French President Emmanuel Macron has unveiled his country’s new nuclear doctrine. Are the changes he has made enough to reassure France’s European partners in the current geopolitical context?

Europe’s reaction to the war in Iran has been disunited and meek, a far cry from its previously leading role in diplomacy with Tehran. To avoid being condemned to the sidelines while escalation continues, Brussels needs to stand up for international law.

Germany's sometimes ambiguous nuclear policy advocates nuclear weapons for deterrence purposes but at the same time adheres to non-proliferation. This dichotomy can turn into a formidable dilemma and increase proliferation pressures in Berlin once no nuclear protector is around anymore, a scenario that has become more realistic in recent years.

France has stopped clinging to notions of being a great power and is embracing the middle power moment. But Emmanuel Macron has his work cut out if he is to secure his country’s global standing before his term in office ends.
