Canada’s allies are wondering if they can still shelter under the U.S. nuclear umbrella

The phrase “going nuclear” used to be figurative, but in today’s political landscape, it seems to be taking on a more literal meaning. With the inauguration of the second Trump administration earlier this year, Washington’s closest allies are beginning to question whether they can still rely on the United States’ nuclear deterrent capability. This uncertainty is especially palpable in South Korea, where the threat of North Korea’s nuclear-armed leader, Kim Jong-un, looms large.

Recent polls in South Korea have shown that nearly three-quarters of the population are in favor of their country acquiring nuclear weapons. While the idea of Canada pursuing nuclear weapons is not on the agenda, some key allies are actively considering this option. Polish Prime Minister Donald Tusk has even mentioned the possibility of Poland accessing nuclear arms through security agreements with France.

South Korea, currently reliant on the United States for extended deterrence, is facing a changing nuclear landscape. North Korea has shifted its nuclear posture from defensive to potentially offensive, raising concerns in Seoul. Despite the growing calls for South Korea to pursue nuclear weapons, former naval officer Ban Kil Joo believes that diplomacy should remain the primary focus in addressing the nuclear threat.

While the cost of maintaining a nuclear arsenal is a deterrent for South Korea, the country has not ruled out the possibility of acquiring nuclear weapons in the future. Diplomatic negotiations with the United States will play a crucial role in determining South Korea’s defense strategy. Former president Yoon Suk Yeol and members of his party have openly endorsed the idea of South Korea going nuclear, while others advocate for a more cautious approach.

As discussions with the Trump administration continue, South Korea is evaluating its defense spending and commitments to its allies. The uncertainty surrounding the U.S. nuclear deterrent has raised concerns among allies like Canada, who fear being sidelined by American foreign policy decisions. The implications of Canada’s sovereignty being challenged have sparked conversations in Seoul about the country’s own security strategy.

In conclusion, the question of nuclear proliferation in South Korea remains a complex and delicate issue. While the idea of acquiring nuclear weapons is gaining traction, the country is treading carefully and emphasizing the importance of diplomatic solutions. As the geopolitical landscape continues to evolve, South Korea’s stance on nuclear weapons will be a critical factor in shaping regional security dynamics.
