1. Order in international relations and liberal international order
To speak of “order” in international relations may seem contradictory, given the relatively
“anarchic” nature of the international system rooted in the sovereignty of States. This
apparent contradiction explains why many theorists avoid using the term. For example,
Raymond Aron refers only to “peace”, which is obviously not the same thing: for him,
international relations have only two forms, war and peace, understanding the latter as
«suspension, more or less lasting, of violent forms of rivalry between political units”,
unveiling “three types of peace: balance, hegemony and empire» (Aron, 1984: 158).
Hedley Bull, on the other hand, prefers to speak of an “international society”, conceived
as a «society of States [...] when a group of States, aware of certain common interests
and values, form a society insofar as they conceive for themselves limits in their mutual
relations by a common set of rules and participate in the activity of common institutions»
(Bull, 1977: 13). Due to their exclusively State-centric character, these views of realist
theorists are contested by liberal, constructivist, functionalist, structuralist, critical and
other theories. And, for example, in a radically different perspective, there are those that
outweigh the role and impact of non-State actors, capable not only of influencing the
decisions of States, but also the international system and even promoting a «global civil
society» (Keck and Sikkink, 1998).
The fact is that among realists, too, there are many who assume the concept of “order”
in IR, such as John J. Mearsheimer (2019: 9), who defines it simply as «an organized
group of international institutions that help to govern the interactions between member
States». In the same vein, Bart MJ Szewczyk (2019: 34) conceives “order” as «a set of
rules and norms to govern State and non-State behaviour, through international law
based on the United Nations Charter, multilateral treaties and political norms resulting
from State practice». However, while Szewczyk believes that the order's primary
objective is «to minimize violence and provide stability. The opposite of it was "disorder",
characterized by war, conflict and uncertainty» (ibid.), Mearsheimer (2019: 9, note 3)
considers that order «is not the opposite of disorder, a term that refers to chaos and
conflict».
Another issue concerns the use, often indistinctly, of the terminologies “international
order” and “world order” – in addition to the “global order” that some refer to (Hurrel,
2007; Lo, 2020). Its use and distinction is rarely explained by the authors (Bertrand,
2004), but it is relevant to us here. Hedley Bull makes this difference, considering that
«The world order is vaster» and «of which the interState system is only a part» (Bull,
1977: 21). He adds that «The world order is more fundamental and primordial than the
international order because the final units of society for all humanity are not States (or
nations, tribes, empires, classes or parties), but individual human beings [...]. The world
order is morally superior to the international order», since its values are those of all
humanity, and not just those that prevail in the society of States (ibid.). Along the same
lines, although with different assumptions, James N. Rosenau, one of the main
representatives of the liberal IR school, developed the “bifurcation” model between two
worlds in what he called the era of “post-international politics”: fundamentally,
“international" characterizes the order in the «State-centric world» among States
«limited by sovereignty», using "post-international", "world" or "global" to describe the
