The post-WWII global framework, including international law, was a fragile agreement primarily enforced by the US. Its erosion is leading to a "might makes right" reality where nations like Russia, China, and the US act unilaterally in their perceived self-interest, abandoning the pretense of shared rules.

Capitalism, socialism, and communism are all growth-based systems predicated on an expanding population to balance labor, capital, and demand. As the world enters demographic decline with shrinking working-age populations, the fundamental assumptions of these 500-year-old models collapse, requiring a complete reinvention of economic theory.

For generations, Western societies have viewed peace and prosperity as the default state. This perception is a historical outlier, making the return to 'dog eat dog' great power politics seem shocking, when in fact it's a reversion to the historical norm of conflict.

By dismantling the post-WWII global order, the Trump administration forces allies to realign with China. As the U.S. retreats from global partnerships, China is positioned to dominate key industries like renewable energy, making the 21st century "the China century" by default as the world moves on without America.

The Western belief that free trade would cause authoritarian states like China to liberalize has proven false. Instead, this policy created a powerful manufacturing competitor whose interests diverge from the West's. The current era of deglobalization is an unwinding of this flawed foundational premise of the post-war order.

The true 'mega risk' is not a single policy but a fundamental shift in the US global role. The post-1945 global economic system, including free trade and dollar dominance, has been built on a foundation of US security and leadership. If that leadership is withdrawn, the entire international order could change fundamentally.

Donald Trump is not the root cause of America's instability but rather a symptom of deeper, long-term issues. These include a decades-long breakdown in institutional trust, the collapse of the "American dream" of upward mobility, and extreme inequality. Focusing solely on Trump distracts from these more fundamental drivers of political crisis.

Mark Carney, former head of the Bank of England and a symbol of globalism, announced at Davos that the old world order is dead. He stated a return to power politics and sovereignty is the new reality, marking a significant shift in elite consensus.

The current wave of global conflict and deglobalization is a direct consequence of a multi-decade populist trend. As younger generations demand fairer economic outcomes ('median outcomes'), governments are forced into protectionist policies, which inevitably create international friction and competition for resources.
