Geopolitics and World Order

Powers, Wars, Resources, Trade, and Technology in International Competition

By Renato Guimarães

How does power work in a world where wars, trade, technology, natural resources, and supply chains have become part of the same strategic competition?

The argument

Geopolitics and World Order offers a broad examination of the forces shaping international relations and determining how states acquire, exercise, and preserve power. Beginning with the foundations of geopolitics—sovereignty, territory, population, security, influence, and alliances—the book explores how competition between nations now extends far beyond military strength into economics, technology, finance, energy, and strategic infrastructure.

The book examines war and military power, great-power rivalry, international trade, economic sanctions, trade wars, natural resources, oil and gas, critical minerals, and the global energy transition. It also explores the increasingly decisive role of global supply chains, semiconductors, artificial intelligence, cybersecurity, data, and digital infrastructure in shaping national power.

Rather than simply asking which countries possess the greatest resources, the analysis focuses on how dependencies are created, exploited, and reduced. Integration into the global economy can generate prosperity while simultaneously exposing countries to disruptions in trade routes, financial networks, technologies, suppliers, and industrial production. Technological leadership can create strategic advantages while producing new dependencies on energy, minerals, advanced chips, manufacturing capacity, and specialized knowledge.

The book also examines the transformation of the international order, including hegemony, unipolarity, multipolarity, economic fragmentation, strategic autonomy, and the changing balance between interdependence and national security.

In a world where nations remain deeply connected while seeking greater control over their vulnerabilities, understanding geopolitics requires looking beyond armies and borders. Factories, ports, currencies, energy systems, digital networks, technologies, resources, and alliances have all become instruments of international power.
