The answer lies in
the structure of global power. The United States does not bear the burden of
its wars alone. Instead, it operates within a system that allows it to
externalise significant portions of the political, economic and financial costs
to the rest of the world. This system is not accidental; it is built on
alliances, market dominance and institutional influence that together sustain
what can only be described as a durable war economy.
First, the
political and diplomatic costs of war are rarely carried by Washington in
isolation. Through alliances such as NATO, the G7 and the Five Eyes, namely, Australia, Canada, New Zealand, the United Kingdom and the United States, responsibility is distributed among
partners. These alliances provide not only military support but also diplomatic
cover, helping to legitimise interventions and diffuse criticism. In effect,
they transform what might otherwise be unilateral actions into collective
decisions, even when the strategic direction is largely driven by Washington.
This shared framework reduces the direct political cost while reinforcing a
sense of global consensus.
Second, war
generates its own economic demand, particularly in the security sector.
Military conflicts heighten global insecurity, and insecurity fuels demand for
weapons, surveillance systems and defence technologies. This demand
overwhelmingly benefits American defence contractors, which remain among the
most advanced and well-funded in the world. As tensions rise, countries
increase their military spending, often turning to US suppliers. In this way,
conflict becomes not just a cost centre, but a revenue stream. The paradox
is striking: instability abroad can translate into economic stability at home,
at least for certain sectors.
Energy markets
provide another layer of advantage. Conflicts in regions such as the Middle
East and parts of Latin America tend to disrupt supply chains and push global
energy prices upward. At a time when the United States has transitioned into a
major exporter of oil and natural gas, these price increases can generate
substantial profits for its energy companies. What was once a vulnerability,
dependence on foreign energy, has evolved into a strategic asset. Rising
prices, while burdensome for many economies, can strengthen the financial
position of American energy firms and contribute to domestic economic
resilience.
Perhaps the most
important factor, however, is the dominance of the US dollar in the global
financial system. This monetary power allows the United States to finance its
wars in ways that few other countries could sustain. By issuing treasury bonds, it
raises vast sums of money that are eagerly purchased by investors around the
world. In essence, global demand for dollar-denominated assets enables
Washington to spread the financial cost of its military activities across the
international system. Other countries, by holding these assets, indirectly
support the funding of US expenditures. It is a system that turns financial
trust into strategic leverage.
Taken together,
these mechanisms explain why the United States has been able to sustain
successive wars without immediate economic collapse. The costs are real, but
they are diffused. They are shared across alliances, embedded in global markets
and absorbed by a financial system structured around the dollar.
Yet this system is
not without limits. Signs of strain are becoming increasingly visible.
Domestically, political divisions are deepening, and public tolerance for
prolonged conflicts is not infinite. Internationally, allies are beginning to
question the arrangement. Calls for greater strategic autonomy, particularly
from countries like France, reflect a growing desire to reduce dependence on
US-led security frameworks. This shift, while gradual, suggests that the
consensus underpinning these alliances may not hold indefinitely.
Beyond the
traditional Western sphere, the Global South is also rethinking its position.
Discussions around de-dollarisation are gaining traction, as countries explore
alternatives to a financial system that concentrates power in one currency.
Some nations are experimenting with new mechanisms, including the use of
digital currencies in trade. Iran, for example, has explored such approaches as
a way to navigate financial restrictions. These developments, while still
emerging, point to a broader search for economic sovereignty.
Importantly, none
of this suggests that the current system will collapse overnight. The
structures supporting US power remain deeply entrenched, and change in global
systems tends to be uneven and slow. However, history shows that even the most
stable arrangements can shift rapidly once certain thresholds are reached. What
appears permanent can, under pressure, transform with surprising speed.
For the Global
South, including Africa, the implications are profound. This is not merely a
question of geopolitics; it is a question of economic strategy and long-term
development. Relying on a system that externalises costs may offer short-term
stability, but it also carries inherent risks. As the global landscape evolves,
there is a growing need to think beyond existing frameworks and to imagine
alternative models of cooperation that are more balanced, inclusive and
sustainable.
The era of
successive wars sustained by diffused costs may not end abruptly, but its
underlying assumptions are being tested. For those willing to look ahead, the real
challenge is not simply to understand this system, but to prepare for what
comes after it.
