However, its success was not inevitable and in fact it faced a serious threat only a few years after it came into force in 1970. India's "peaceful nuclear explosion" (PNE) in May 1974 rocked the nuclear nonproliferation regime and cast doubt on the NPT. And yet in the two years after the PNE, several significant countries ratified the treaty. Why did states that had been notable holdouts from the NPT, like Italy, Japan, and South Korea, ratify the treaty soon after the Indian nuclear test? This paper finds that the PNE galvanized pro-NPT forces in the US and Canada, leading to changes in nonproliferation policy. In particular, it led them to threaten to withhold access to nuclear technology and materials unless the holdouts ratified the NPT. It also motivated Henry Kissinger to change his secret advice to Japan that the US did not want Japan to ratify the NPT in order to keep the People's Republic of China unsure about Japan's nuclear intentions.

Contrary to the prevailing understanding of norm violation as a strictly negative phenomenon that leaves regimes damaged, we show that normative deviance is, under certain conditions, a stressor that helps predominantly antifragile systems learn, improve, and adapt to changes in both internal and external environments. We apply this conceptual framework to the case of the NPT regime and the prominent violations of its nonproliferation norms by India in the 1970s (as a "contestation from outside") and Iraq in the 1990s (as a "contestation from within"). Our findings question the prevailing catastrophizing narrative about the strictly negative impact of norm violations on regime stability and contribute to contemporary scholarly debates about norm dynamics within the NPT.

Despite being proven ineffective as a coercive tool or deterrent, the international community has actively withheld recognition in numerous instances of territorial conquest since the 1930s. Joseph O'Mahoney systematically analyses 21 case studies--including the Manchurian Crisis, the Turkish invasion of Cyprus and Russia's annexation of Crimea--to explore why so many states have adopted a policy of non-recognition of the spoils of war. By drawing on historical sources including recently declassified archival documents, he evaluates states' decision-making. He develops a new theory for non-recognition as a symbolic sanction aimed at reproducing common knowledge of the rules of international behaviour.

In practice most explanations of behavior in political science rely, whether implicitly or explicitly, on some attribution of motive to actors. However, motive and the attribution of motive to individuals and especially corporate actors, like the state, is rarely theorized in empirical studies, either in terms of what it means conceptually, or in terms of how attribution of motive is dealt with methodologically. This paper explores some of these issues and apply them to the practice of political science, with particular reference to examples in International Relations. In particular, this paper articulates the fundamental problem of motive attribution, that we cannot introspect the motives of other actors, and lays out its implications. There are three possible methodological responses to this fundamental problem; 1) assume or deduce a po...

Why? This article uses an investigation of the Manchurian Crisis to reconceptualize nonrecognition as a symbolic sanction against a norm violation. Existing accounts often view symbolic sanctions like nonrecognition as either failed attempts at coercion or mere posturing for domestic audiences. Against this view, this article explains how collective symbolic sanctions create or recreate common knowledge of what the rules of international behavior are in the face of a lack of effective rule enforcement. This common knowledge, or intersubjective understanding, shapes future expectations and interpretations. Nonrecognition of the spoils of war is thus a means to reinforce the norm of nonaggression within international society by reestablishing a shared valuation of the rule.

Dominant conceptions of institutional change in International Relations theory are based on the idea that it is the result of a shift in power: new actors become able to impose their vision on the world. However, the source of change need not be the power or preferences of actors in society, but could come from the internal dynamics of the rule system governing these actors. This article develops recent research in this area by linking Sandholtz’s model of norm change to recent dynamic institutionalist work and exploring and specifying particular mechanisms, or types of tensions, in rule systems that produce change. Institutions and complexes of rules exhibit rule tensions: inconsistencies, ambiguities, and inadequacies that can lead to disputes over the application of the rules. Actors then have to solve problems or disputes over rule interpretation. Change can thus occur without the introduction of new actors or a shift in ...

However, we cannot access other people's reasons for action the same way that we perceive our own; we cannot introspect the reasons of other actors. This paper provides a unifying framework that delineates different types of knowledge claims regarding reason attribution. There are three possible methodological responses; 1) assume a possible reason and explain behavior in terms of that reason; 2) avoid the direct attribution of reason to individuals and locate explanatory leverage at an analytical level beyond the individual actor reason; and 3) use empirical evidence to adjudicate between possible reason. Excessive skepticism of evidence of reasons lessens our understanding of the causes of action. When using empirical evidence, contrary to existing arguments the paper shows that private settings do not systematically favor the true revelation of reasons. The paper also proposes a general principle, consilience, that allows evaluation of empirical claims of reason attribution that subsumes several existing methodological considerations, organizes them, and gives a consistent means of choosing between alternative reason attributions.

Rather than using the pure force of abstract moral reasoning, states often try to move the locus of contestation to an arena where they can make practical progress—the evidence or the empirical facts in support of their argument. This paper analyzes how states try to bolster their position first by constructing an argument in which an action represents part of their argument and then by performing that action to make the argument seem more convincing. I call this mechanism rhetorical adduction. The paper challenges theories of communication that deny a causal role to the content of normative arguments and diverges from a leading view on argumentation that arguments have their effects through persuasion. Integrating strategic argumentation theory with theory from psychology about how people make choices based on compelling reasons rather than cost-benefit analysis, I also use theory from sociology on how people re...

" I illustrate the mechanism using a case from the Indo-Pakistani war of 1971 when initial resistance to recognizing the putative state of Bangladesh after India's invasion of East Pakistan was reversed as a result of an argument that Indian troop withdrawal meant that international norms were not violated.

The idea of a reason behind an action is an 26 important part of the debate surrounding causation in the social sciences 27 and in International Relations (IR). 1 The word 'cause' originally meant a 28 reason for an action, coming from the Latin word causa meaning 'purpose' 29 or 'reason' (Martin 2011, 30). In practice, most explanations of behavior in 30 political science rely, whether implicitly or explicitly, on some attribution of 1 Not all claims of social science causation involve attributing reasons for action, as I show below.

Recent research has claimed that British colonialism is largely responsible for the criminalization of homosexuality around the world. This article utilizes a newly constructed dataset that includes up-to-date data on 185 countries to assess this claim. We find that British colonies are much more likely to have criminalization of homosexual conduct laws than other colonies or other states in general. This result holds after controlling for other variables that might be expected to influence the likelihood of repressive lesbian, gay, bisexual and transgender (LGBT) rights legislation. However, we also find that the evidence in favour of the claim that British imperialism 'poisoned' societies against homosexuality is weak. British colonies do not systematically take longer to decriminalize homosexual conduct than other European colonies.
