Trump's re-election shatters the perception that his first term was an aberration. Allies now see his brand of foreign policy as a persistent feature of the American political landscape. Any future US administration, even a traditional one, will face deep skepticism as partners anticipate the pendulum could swing back.

The United States' greatest strategic advantage over competitors like China is its vast ecosystem of over 50 wealthy, advanced, allied nations. China has only one treaty ally: North Korea. Weakening these alliances through punitive actions is a critical foreign policy error that erodes America's primary source of global strength.

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 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 If that leadership is withdrawn, the entire international order could change fundamentally.

Despite claims of being 'realist,' Trump's foreign policy is fundamentally anti-realist. By alienating allies, cutting R&D, and acting imprudently, it undermines the very sources of long-term American power—partnerships and technological superiority—that a true realist would seek to preserve.

The US's global power is eroding due to debt and inflation. Trump's aggressive foreign policy is not random; it's a high-risk strategy to press America's current advantage and re-establish dominance before rivals like China can take over. The only alternative is accepting a managed decline.

Trump's direct, aggressive actions often achieve immediate goals (first-order consequences). However, this approach frequently fails to anticipate the strategic, long-term responses from adversaries like China (second and third-order consequences), potentially creating larger, unforeseen problems down the road.

Stephen Walt defines Trump's foreign policy as 'predatory hegemony,' a unique strategy where a dominant power uses its leverage to extract concessions and tribute from everyone, including long-standing allies. This departs from traditional great power politics, which is typically predatory only toward rivals.

The administration's aggressive, unilateral actions are pushing European nations toward strategic autonomy rather than cooperation. This alienates key partners and fundamentally undermines the 'Allied Scale' strategy of building a collective economic bloc to counter adversaries like China.
