Trump Is Gutting America’s Core Geopolitical Advantage

Foreign Affairs | Robert B. Zoellick

The Trump administration is undermining the North American partnership with Canada and Mexico through high tariffs, economic coercion, and threats of military intervention. Friendly relations with neighbors enhance security and economic gain, whereas weak neighbors export trouble. Historically, U.S. leaders recognized that continental harmony is the starting point of global strategy, contrasting with rivals like China and Russia that manage numerous hostile borders.

William Seward first understood that continental control yields global influence through free choice rather than coercion. Twentieth-century integration culminated in the North American Free Trade Agreement in 1992, which advanced economic growth, investment, and strategic reconciliation. Opponents once feared major job losses, yet NAFTA proved an economic and strategic success, with cross-border trade soaring into the hundreds of billions of dollars. By alienating natural partners, current policies destroy a precious geopolitical asset that has long anchored American power.

Comment

Tariff escalation and coercive rhetoric directed at Ottawa and Mexico City disrupt the integrated supply chains anchored by the United States-Mexico-Canada Agreement. This friction strains joint border security architecture like the North American Aerospace Defense Command, weakening the continental strategic depth that traditionally underpins global power projection.

Strategic Question for Discussion
To what extent does sustained economic coercion within the United States-Mexico-Canada Agreement framework accelerate supply chain decoupling rather than achieving domestic re-industrialisation goals?
The available evidence points toward rapid fragmentation rather than orderly reshoring. Imposing unilateral tariffs without matching domestic manufacturing capacity creates severe input bottlenecks for key industries, ultimately driving up production costs rather than securing strategic autonomy.
