In the weeks following Donald Trump's return to the White House, global leaders and political analysts have been left grappling with the implications of his foreign policy strategies, marked by unpredictable tariffs, significant alliance renegotiations, and provocative territorial claims. The uncertainty surrounding whether his rhetoric is mere bluster or a serious intent has left many in a state of confusion regarding the direction of U.S.-Canada relations.

While some observers deem Trump's policies incoherent, a closer look reveals they might be rooted in a third geopolitical framework: continentalism. Unlike traditional concepts of isolationism and internationalism, continentalist geopolitics suggests a worldview that divides nations into zones of influence, dominated by major powers. This theory, although largely overshadowed in modern foreign policy debates, has historical roots going back to the 19th and early 20th centuries.

Historically, continentalist geopolitics focused on designated "Great Powers," where not every region held equal significance. In this paradigm, the United States, given its vast financial, industrial, and natural resources, is inclined to wield control over nearby territories and essential transportation routes, especially those it perceives as within its sphere of influence. This arrangement creates a scenario where countries like Canada and Mexico may find themselves pressured to deepen their economic ties and infrastructural dependencies on their southern neighbor.

High-profile political statements from figures like Ontario Premier Doug Ford, who advocates for fortified continental ties via an "AmCan arrangement," only serve to affirm Trump’s desired strategy of solidifying economic and political dominance over neighboring states.

The continentalist approach also emphasizes geographic and strategic territories that hold significant economic value—Panama's canal being a prime example—along with resources located in Greenland, whose strategic importance has grown as the Arctic continues to thaw. These areas, along with Canada, became focal points for Trump early in his second term, signaling a concerted effort to apply economic and political pressure on neighbors.

Today's geopolitical landscape is more complex than ever, influenced by multipolarity and shifting alliances. Although continentalism isn’t isolationist, it reflects a realization that as American power diminishes in a connected world, nations further from the U.S. might forge alliances to counter American influence. In this context, Secretary of State Marco Rubio underscored the notion that the current global order might shift toward a multi-great power system, particularly as tensions with countries like China and Russia rise.

Under this continentalist strategy, America isn't entirely severing itself from the global economic framework. On the contrary, it aims to encourage trade and technological exchanges. However, these interactions would hinge upon a self-sufficient America, well-protected from external economic shocks. This translates to increased burdens placed on NATO allies for defense budgets and minimized commitments to global stability.

Moreover, the continentalist lens suggests that distant conflicts should be managed by the powers nearest to them, encouraging the U.S. to take a backseat in international coalitions, which significantly diminishes its global engagement. Foreign aid could morph into a tool for asserting national interests rather than a commitment to universal stability, an idea that echoes the sentiments of some influential voices in tech and politics.

The potential rise of continentalism in U.S. foreign policy has garnered insufficient attention in Canada, where the implications could be profound. It remains uncertain whether the Trump administration’s actions presage a widespread adjustment towards this geopolitical model. However, the historical precedent for this approach has often led to conflict and turbulence.

For Canada, a neighbor adopting continentalist geopolitics signifies a monumental shift in international relations fraught with challenges and risks. Canadians must brace themselves for the potential ramifications of this strategic shift—whether to navigate rough waters or to seize opportunities to redefine their diplomacy in an increasingly tumultuous global landscape.
