Geography is permanent. What cannot be risked is the gradual normalization of
treating the United States as an adversary across multiple domains.
Introduction
After trade talks collapsed in late August 2026, Washington imposed 50 percent
tariffs on roughly $20–28 billion of Canadian goods. Ottawa responded by
announcing matching retaliatory tariffs, rate-for-rate and dollar-for-dollar,
effective 8 September, targeting U.S. steel, dairy, appliances, agricultural
equipment, pulp and paper, electronics, and related products. Canada thus finds
itself in an open, declared “dollar-for-dollar” tariff conflict with the United
States. Prime Minister Mark Carney framed the moment starkly: “You’re at war
when you get attacked. We got attacked.”
Clausewitz, On War and Friction
On War,
seminal work by the Late Prussian General Carl von Clausewitz, published between 1832 and
1835 by his wife remains the most controversial and influential source of
strategic military thinking. One of Clausewitz's best-known quotes is "War is
the continuation of policy with other means." The language of war invoked by PM
Carney does not seem to be accidental. Economic coercion of this intensity
carries the same structural tendencies that Carl von Clausewitz identified in
armed conflict. War, he futher argued, has a logic of its own. Friction—the
accumulation of difficulties, imperfect information, chance, organizational
resistance, and secondary effects—distinguishes real conflict from plans on
paper. What begins with limited objectives can, through friction, expand,
redefine its purposes, and generate outcomes neither side fully intended. The
same dynamic operates in a sustained tariff war between deeply integrated
neighbours.
Canada’s Geography, History and Reality
Canada’s geography, history,
and economic reality make the stakes uniquely high. The two countries share the
world’s longest undefended border and a continental defence architecture built
on trust. NORAD remains the institutional expression of that shared security; also, NATO binds the two North American neighbours in the broader transatlantic framework.
U.S. goods and services trade with Canada totaled an estimated $872.3 billion in
2025, down 4.6 percent from 2024. Of this goods trade totaled an estimated
$715.5 billion. U.S. goods exports to Canada in 2025 were $333.6 billion, down
4.8 percent from 2024. U.S. goods imports from Canada totaled $381.9 billion in
2025, down 7.2 percent from 2024. The U.S. goods trade deficit with Canada was
$48.3 billion in 2025, a 21 percent decrease over 2024.

Supply chains, energy
systems, labour markets, and defence production are interwoven to a degree
unmatched by almost any other pair of sovereign states. This interdependence was
constructed over generations on the assumption of reliability, trust and mutual
restraint. When that assumption erodes, the potential for spillover into
non-economic domains grows.
A significant segment of the Canadian public (56%)
appears to support Carney’s refusal to accept what he described as unfair,
uneconomic last-minute U.S. terms. That political backing is understandable but
is a double-edged sword in the present situation. Sovereignty, industrial
capacity, and the defence of workers and communities are legitimate national
interests. Matching tariffs “dollar for dollar” signals resolve and seeks to
impose reciprocal costs. Yet resolve is not the same as strategic success.
Friction ensures that the simple act of retaliation will produce complications:
higher prices for Canadian consumers and businesses, disrupted supply chains,
pressure on specific regions and sectors, retaliatory escalation from
Washington, which has already been announced, and the gradual politicization of
issues once insulated from trade disputes.
Independent Logic of Conflict
The
danger is precisely the independent logic of conflict. Once both sides treat the
confrontation as existential or zero-sum, secondary objectives multiply.
Questions of market access can bleed into regulatory alignment, investment
screening, energy policy, or even the practical functioning of joint
institutions. The fog of economic war—competing narratives about who demanded
what, last-minute changes, domestic political pressures on both sides of the
border—makes it harder to maintain clear political control over ends and means.
Clausewitz warned that the difficulties accumulate and that a powerful will can
crush obstacles only by risking damage to the machine itself. In this case the
“machine” is the dense web of cooperation that has underwritten Canadian
security and prosperity for decades.
Canada’s Vital National Security Alliances
Canada’s two vital national security alliances with the United States—NATO and
NORAD—must remain outside the tariff battlefield. Continental air and maritime
warning, aerospace defence, and the broader collective defence commitment are
not bargaining chips. Geography makes them non-negotiable for both countries;
history and institutional design make them operationally inseparable. Allowing
trade friction to corrode the habits of cooperation, information sharing, or
joint planning that sustain these alliances would convert a serious but
containable economic dispute into a strategic self-inflicted wound. The same
logic applies to the broader defence-industrial relationship and to the everyday
trust that enables seamless border management and emergency response.
Statesmanship and Restraint
Caution is the better part of valour here. Actions
must remain subordinate to a clear political purpose: protecting Canadian
workers and industries, preserving sovereignty, and restoring a stable,
rules-based economic relationship on terms that both sides can sustain. That
purpose must not be allowed to redefine itself under the pressure of reciprocal
pain, domestic applause, or the temptation to “win” a contest that neither
country can truly win without lasting damage. Friction will generate interim
adverse outcomes—lost markets, higher costs, strained provincial-federal
coordination, and diplomatic frost. The test of statesmanship is whether
political leaders keep those outcomes from becoming the new, expanded goals of
the conflict. Perceptive Canadian citizens understand that Canada cannot simply opt out
of North American economic reality. Diversification of trade is prudent and
overdue, but it is a medium-term project, not an immediate substitute for the
U.S. market. Retaliation can be calibrated, temporary, and tightly linked to
specific U.S. measures. Support packages for affected workers and firms, already
announced in the billions, can help cushion the impact. What cannot be risked is
the gradual normalization of treating the United States as an adversary across
multiple domains. Geography is permanent. Alliances of the depth of NORAD and
NATO are not easily rebuilt once trust is spent.
Concluding Thoughts
The present
tariff war is real. It carries costs, and those costs will be felt. Yet it
remains, for the moment, an economic conflict. Clausewitz’s insight is that
conflict tends to escape its original bounds unless political authority
continually reasserts control over its purposes and limits. Canada’s history of
interdependence, its security architecture, and its long-term national interest
all counsel discipline. Match the tariffs as the necessary response. Defend
Canadian interests without apology. Explore and expand inter province and
international supply chains and trade partners. PM Mark Carney’s focused visits
to various international destinations have already started the process. This
process needs to be expedited to cater for the worst-case situation. However, it
would be prudent to continue to quietly engage with various like-minded stake
holders across the border with an aim to seek an end to this needless
confrontation, which not only destroys a win-win arrangement for both countries
and hurts citizens on both sides, but most of all may lead to a loss of trust
between the two, besides other unintended consequences.
It is important to
not let friction, fog, and the independent logic of confrontation redefine the
relationship into something neither geography nor history can sustain. Caution,
in this case, is not weakness. It is the recognition that some forms of damage,
once inflicted, cannot be undone once it crosses a point of no return, even by a
later change of government or a new round of talks.
