Among Nations (1948), Morgenthau defined international politics as a perpetual struggle for power, and argued
that states defined their national interest in power terms first of all, and the survival and security of the state had
to be secured first of all by the state's leaders. Moral considerations do have some relevance, but they cannot
trump the fundamental need for protection of the state. Contemporary scholars of realism, such as Mearsheimer
(2021) and Wohlforth (2020) apply these arguments to contemporary international politics and argue that the
renewed great-power competition testifies to the analytical power of realism, at least in the measurement of
expectations that institutions alone can maintain cooperation.
An important realist concept is the security dilemma, which was first discovered by John Herz and developed
by Robert Jervis. The security dilemma results from the fact that it is extremely difficult to distinguish between
defensive military preparations and offensive preparations in an international system where there is no central
authority. When one state develops greater military capacity for protective purposes, others may see this as
threatening and respond by developing their own forces leading to tension and arms races even where there is
no aggressive intent. This dynamic has direct consequences to human development: resources that are spent for
military competition are unavailable for education, healthcare and infrastructure.
Structural Neorealism: Anarchy, Balance of Power, and Systemic Constraints
A major development within the field of thought in realism came at the work of Kenneth Waltz and his book
Theory of International Politics (1979). Waltz shifted the analysis from the nature of human being and individual
state behaviour to the structure of international system as a whole. He argued that it cannot be explained in terms
of the motivations or domestic politics of individual states to sustain recurring patterns of competition and
conflictrators, rather they are the product of the structure within which all states must operate.
For Waltz, what characterises the international system is anarchy namely the lack of any authority above the
level of states. Because no global authority is available to guarantee security, various states have to depend
primarily on their own capacities. Survival is based on a state's relative power and strategic decisions. This
structural situation encourages characteristic behaviours: balancing against powerful rivals, keeping up deterrent
military capacity, and avoiding dangerous dependence on others for critical security needs. The distribution of
capabilities among states defines the overall nature of the system and limits the options among all states in the
system.
Contemporary neorealist scholars use Waltz's framework as a way to describe contemporary power shifts,
particularly the rise of China and the developing relationship between Beijing and Washington that is widely
perceived as the defining geopolitical contest of our time. Power transition theorists, including Tammen and
Kugler (2021), are concerned with questions regarding whether these power transitions give rise to conflict or
peaceful accommodation. From a neorealist perspective, as China's power approaches the US, structural
pressures for tension may escalate regardless of declared intentions on either side. This rivalry would have grave
consequences for the development of mankind: major conflict between leading powers would disturb the
development finance, climate cooperation and the global health efforts, seriously undermine the provision of
international public goods.
Geopolitical Thought: Territory, Strategic Space, and the Return of Geography
Geopolitics looks at the relationship between geography, territory, natural resources and political power. Early
geopolitical thinkers like Halford Mackinder, Alfred Thayer Mahan, and Nicholas Spykman wrote at the turn of
the twentieth century, and their thoughts have been given new attention in recent years, as scholars advance the
idea that geography still influences world politics as a result of globalisation and technological change (Kaplan,
2019; Grygiel, 2022). Control over the sea routes, energy resources, and strategically important locations is still
an important determinant of political and economic influence.
Contemporary geopolitics involves new competitive arenas. The rivalry between the United States and China is
now expanding across the area of artificial intelligence, semiconductor manufacturing, quantum computing and
the infrastructure for telecommunications systems - a contest that many analysts refer to as a key strategic
struggle of the twenty-first century (Drezner, Farrell, and Newman, 2021). Control of key technologies provides
