The Future of Middle Powers in Global Politics

Mark Carney Pitches Trillions at Toronto Summit Amid U.S. Trade Strains

Prime Minister Mark Carney welcomed dozens of investors to Toronto, Ontario, on September 15, 2026, during the inaugural Canada Investment Summit. According to American Purpose, the gathering served as a clear show of strength for a Canadian leader locked in a difficult trade war with Washington. The pitch for trillions of dollars in investments across Canada marks a concrete step in Carney’s broader push for middle power self-reliance, nearly a year after he first called for collaborative middle power strategies at the World Economic Forum.

Following the Toronto summit, Carney traveled to Europe. During that diplomatic tour, European Commission President Ursula von der Leyen revealed that the European Union is planning to invite Canada to join the bloc as an associate member, as reported by American Purpose.

The Dilemma of Middle Powers Under the Trump Administration

Despite Carney’s proactive posture, many global middle powers remain hesitant to loosen ties with Washington. As detailed by American Purpose, the United States under President Donald Trump has fundamentally upended the post-World War II international order by imposing tariffs on close allies, threatening to annex the territory of fellow NATO members, and launching a prolonged military stalemate with Iran.

Yet, economic and military dependencies run deep. Canada and China stand out as the sole nations to retaliate against U.S. tariffs. By contrast, the European Union finalized a trade deal with Washington that left a 15 percent tariff on most European imports intact—a compromise critics argue only deepens Europe’s reliance. Meanwhile, nations like Japan and South Korea have reacted with alarm to White House policies but judge that breaking away carries too high a risk given an aggressive Beijing in their own backyard. In Latin America, countries such as Colombia and Argentina are actively drawing closer to Washington, viewing the current U.S. administration as a welcome ideological ally.

Evaluating the Two-Year Window for Strategic Autonomy

According to Imran Bayoumi, deputy director and resident fellow with the GeoStrategy Initiative at the Atlantic Council’s Scowcroft Center for Strategy and Security, the next two years—bookended by the U.S. midterm elections and the 2028 presidential election—offer a crucial window of opportunity. Governments must decide whether Trump’s disruptive foreign policy represents a permanent structural transformation or merely a temporary historical rupture.

Bayoumi notes that while a shift in control of the U.S. House or Senate during the upcoming midterms might tempt allies to bank on a return to conventional American diplomacy, transactional geopolitics are likely to outlast the current presidency. Consequently, analysts argue that middle powers should use this narrow window to build alternative diplomatic, economic, and security frameworks, ensuring they retain bargaining power when their national interests diverge from Washington's.
