Since the end of World War II, the global order has undergone significant transformations, leading analysts to identify three distinct phases of geopolitical tension. The first Cold War spanned from 1947 until the fall of the Berlin Wall in 1989, followed by a period of relative stability from 1990 to 2014—often described as “cold peace.” The more recent phase, sometimes called the second Cold War, extended until 2024 and was marked by increasing alignment between Russia and China amid rising global pressures.

This second Cold War differed from its predecessor by expanding competition beyond military arenas into digital infrastructure, artificial intelligence, cybersecurity, and financial systems. Notably, economic tools such as the exclusion of Russia from the SWIFT payment system illustrated this diversification. Proxy conflicts in regions such as Ukraine and Syria also persisted during this period. Some commentators, however, argue that the current global situation represents a departure from this pattern, citing fractures within the Western alliance as evidence of a fundamentally different phase.

Barry Buzan, an international relations expert at the London School of Economics, has highlighted the growing tensions within the Western bloc, particularly among traditional allies. These internal disputes have manifested in ongoing trade conflicts and increased geopolitical strains, including concerns about the sovereignty of territories once considered allied. Journalist Gideon Rachman has characterized these dynamics as a “trans-Atlantic divorce” held together largely by historical entanglements, notably the longstanding U.S. military presence in Europe, which still comprises over 40 bases and around 85,000 troops.

Amid these strategic shifts, the global economic center of gravity continues moving eastward, reflecting the rising influence of China, India, and Southeast Asian nations. These countries generally seek to avoid provoking large-scale conflict, as stability remains essential for their development objectives. Nonetheless, they approach global uncertainties—particularly in technology, finance, and demographic trends—with caution.

Recent international forums have underscored the prevailing sense of uncertainty. Events such as the World Bank and IMF annual meetings, the United Nations Forum on Financing for Development, and the Santa Marta Energy Conference have all highlighted concerns related to security, sovereignty, and sustainability across key sectors including water, energy, food, technology, and finance.

Energy discussions at the Santa Marta conference, attended by representatives from 57 countries, emphasized the importance of balancing climate goals with energy sovereignty and economic security. Despite commitments to phase out fossil fuels by 2050, participants noted the need to ensure stable, diverse energy supplies amid ongoing global conflicts, such as the war in the Middle East. Brazilian delegate Ana Toni stressed the interconnectedness of economic security and control over energy resources, while British climate envoy Rachel Kyte highlighted the urgency of reducing fossil fuel dependence to address broader instability.

The roles of sovereignty, security, and sustainability often overlap but require distinct approaches. Sovereignty pertains to national control over energy production and supply chains; security focuses on ensuring availability and price stability; and sustainability integrates environmental concerns with long-term economic and intergenerational equity.

As geopolitical tensions persist and global crises multiply, bridging the gap between stated priorities and practical implementation remains a formidable challenge. The complexity of emerging rivalries, coupled with diminished trust among key players, continues to test the effectiveness of policies aimed at advancing sovereignty, security, and sustainability in critical sectors worldwide.
