Following the collapse of the Bretton Woods system, the international community sought new stability in the financial system and the assurance of sustained growth. The crisis that began in 2007-2008 has revealed weaknesses that affected advanced economies first and foremost. Efforts have since been made to consolidate the international financial architecture, to coordinate macroeconomic policy, and to improve foreign exchange relations, even if this latter objective has proven complex.

The trade war between the United States and China is not only due to Donald Trump’s impulsiveness. Its roots are in fact profound and follow three structural changes in the multilateral trading system: the reversal of comparative advantages, the now central role of certain developing countries, and the re-balancing of power that makes coordination between states difficult. In this context, the future of world trade has yet to be written.

Renewable energies are experiencing rapid growth, due not only to their limited impact on the environment but also to shrinking costs. To fight climate change, new investments in low carbon technologies are necessary. Apart from its positive aspects, the energy transition carries risks, notably geopolitical. The notion of energy security will be profoundly modified. These risks can be anticipated and managed.

Forecasting in areas of strategy is particularly delicate as predictions may impact the course of events. While several major trends in the evolution of conflicts during the next decade can be identified, precise forecasts are impossible. Yet one thing is certain: in the next 10 years, decision-makers face unknown risks of significant consequence.

Demographic forecasting is not an exact science. UN projections, which suggest that the world population may rise to 11.2 billion in 2100, could be overestimates. Indeed, fertility could fall more rapidly and life expectancy may rise less than expected. The Sahel is set to experience the most spectacular demographic explosion, but this will not necessarily lead to massive migration to Europe.

The notion of power has long been a topic of study in international relations. In the coming decade, the evolution of power will be characterized by the dynamics of concentration and dispersion. On the one hand, the global system will be marked by the clash of two superpowers, the United States and China. On the other hand, capacity for individual action will proliferate through information and communication technologies.

Montesquieu’s theory of “doux commerce” has never ceased to be debated.

The Great War has shaped many 20^th century practices and norms.

The First World War gave rise to the emergence of the discipline of international relations, but it was the Second World War and the Cold War that fostered its development.
