Tensions between the United States and Iran escalated dramatically last week, as President Donald Trump’s initial threats gave way to a surprising pause. The US, despite its overwhelming military strength, seems to be caught once again in a complex struggle that mirrors past conflicts, raising questions about America’s ability to secure lasting victories abroad.

Military Might Meets Strategic Reality

Last Tuesday, President Trump warned that an entire civilisation could be wiped out overnight, only to delay any immediate military action by two weeks. This pause opens a narrow window for diplomatic efforts involving the US, Iran, and Israel, the latter closely watching from the sidelines. Despite the US’s superior firepower, Iran holds a critical advantage: control of the Strait of Hormuz. This narrow waterway is a global choke point for oil shipments, influencing gasoline and diesel prices worldwide, and by extension, impacting international stock markets.

The Strait of Hormuz is more than just a geographic feature; it serves as a key geopolitical lever. Iran’s control here means it can disrupt global energy supplies, affecting economies well beyond the Middle East. For Canada, a country deeply integrated into global markets and reliant on stable energy prices, the stakes are high. Any conflict that threatens oil flow could reverberate through Canadian gas stations and financial markets.

Echoes of Past Failures

History isn’t exactly on America’s side in this one. The current tensions echo previous US conflicts where military superiority didn’t translate into clear victories. Vietnam, Afghanistan, and Iraq all offer cautionary tales.

In Vietnam, the US military often won battles, but public opinion shifted against the war as televised images and rising casualties eroded support. The war was lost not on the ground but in American living rooms, with 58,000 soldiers’ deaths becoming a grim tally that shifted the nation’s mood.

Afghanistan showed a similar pattern. The US spent nearly 20 years trying to build a stable government there, pumping billions into nation-building efforts. Yet, the institutions it supported crumbled under the Taliban’s relentless push.

Having military strength alone didn’t bring peace or stability.

Iraq’s 2003 invasion toppled Saddam Hussein, but what followed was chaos that destabilized the region for decades. The vacuum left behind fueled sectarian violence and extremist movements, creating a ripple effect that complicated US relations with allies and adversaries alike.

The Roots of Repeated Missteps

Analysts say these repeated failures stem from overconfidence and poor strategic planning by US leaders. Successive presidents have often lacked deep understanding of the complex realities on the ground before committing troops. There’s been a tendency to assume American military and intellectual superiority will guarantee success.

Mastheads

Right now, groupthink and bureaucratic inertia have also played roles. War plans sometimes overlook critical scenarios, like the closure of the Strait of Hormuz during conflict, a possibility repeatedly flagged in war games but seemingly ignored in decision-making.

Either President Trump wasn’t fully briefed on these risks, or he chose to ignore them.

Political pressures and alliances make the situation even more complicated. Senator Marco Rubio’s initial admission that the US would have to back Israel’s preemptive strike on Iran—later walked back—reveals the influence of regional allies and the tightrope Washington walks. The US could have told Israel to delay or proceed independently, but instead, it appeared ready to jump into a conflict with unclear objectives.

Implications for Canada and the World

Canada isn't directly involved militarily, but the economic and political consequences are significant. Energy markets are particularly sensitive to instability in the Gulf. Canada’s oil exports and energy sector investments could face volatility if supply routes are threatened or if global prices spike suddenly.

Politically, Canada must balance its alliances, including its close ties to the US and its commitment to multilateral diplomacy. The Canadian government has historically advocated for peaceful resolutions, and an escalation in the Gulf would challenge Ottawa’s ability to influence outcomes while protecting Canadian interests abroad.

There’s also the matter of global stock markets. Investors worldwide react swiftly to uncertainties in key regions. A conflict that disrupts oil shipments could trigger broader market instability, affecting pensions, savings, and investment portfolios of Canadians.

And then there’s the human angle. While Canada hasn't deployed troops directly to confront Iran, Canadian citizens and dual nationals in the region could face heightened risks.

The government would need contingency plans for evacuation and consular support.

Looking Ahead: Lessons Not Learned?

What’s striking is how the current Iran tensions reflect a pattern of repeated US miscalculations. The assumption that military power alone can solve complex geopolitical problems keeps leading to protracted conflicts without clear victories.

As the US and Iran step back from immediate hostilities, the world watches closely. Will diplomacy prevail? Or will the cycle of threats, delays, and brinkmanship drag the region—and the globe—into deeper uncertainty?

Canada’s role may be limited in direct terms, but the country can't afford to ignore these developments. The economic shocks from disrupted energy supplies and the political fallout in international relations mean that Ottawa will have to stay engaged, balancing caution with the need to support peaceful solutions.

The question remains: Has America already lost another war before it started? History suggests caution. For Canada and its allies, the priority should be avoiding the mistakes of the past and pushing for negotiations that prevent further destabilization.
