A stark warning from a former top NATO commander has revived an old fear in European capitals and Ottawa: the alliance may need to stand on its own. General Richard Shirreff, a former NATO deputy supreme commander, argues that allies must plan for security even if the United States steps back.
“When Nato’s strongest member threatens one of its weakest, the alliance’s foundations crack. But Europe and Canada can now start preparing for a world without Washington,” said General Richard Shirreff.
His comment follows years of anxiety over Washington’s long-term commitment. It comes as war rages in Ukraine, defense budgets rise, and voters on both sides of the Atlantic debate foreign policy costs.
A Fraying Security Guarantee
For decades, the United States has anchored NATO’s defense, providing troops, logistics, nuclear deterrence, and the largest share of spending. Analysts estimate the U.S. accounts for about two-thirds of NATO defense outlays. That scale has shaped planning, procurement, and command structures since 1949.
Political shocks have tested that model. In early 2024, a former U.S. president suggested he would not protect allies that fail to meet spending targets and hinted he would “encourage” Russian pressure. The remark rattled Europe, especially in frontline states near Russia. Leaders in the Baltics and Poland warned that deterrence depends on credible promises, not conditional ones.
Shirreff’s message lands in that context. He has long urged European governments to treat collective defense as an urgent task, not a distant ideal. His latest call sharpens the question: What if the anchor shifts?
Europe and Canada Reassess Defense
The shock of Russia’s 2022 invasion of Ukraine pushed many allies to increase defense budgets. NATO’s 2 percent of GDP target, once ignored by many, is now within reach for more members each year. Several countries have launched multi-year plans to rebuild ammunition stocks and air defenses.
Canada faces a similar reckoning. It is strengthening continental defense with the United States through NORAD modernization and Arctic surveillance. Ottawa’s recent policy updates outline new investments in ships, surveillance aircraft, and northern infrastructure. Meeting alliance targets remains a political fight, but the trajectory is clearer than before.
European Union initiatives also aim to fill gaps. Joint procurement schemes, the Strategic Compass, and projects under PESCO seek to integrate logistics, training, and munitions production. None replace NATO, but they can reduce dependence on unique U.S. capabilities.
Budgets, Industry, and Readiness
Money alone is not enough. Stockpiles of artillery shells and air defense missiles remain tight after heavy transfers to Ukraine. Production lines are expanding, yet industry warns that stable, long-term contracts are essential. Troop readiness, maintenance, and training cycles must match new kit.
Shirreff’s warning points to practical steps that do not wait on Washington. Governments and industry leaders describe a near-term checklist:
- Lock in multi-year ammunition and missile orders to scale production.
- Build layered air defense and counter-drone systems for cities and bases.
- Harden energy, ports, and rail against sabotage and cyberattacks.
- Expand integrated air and missile defense across NATO’s east.
- Strengthen Arctic surveillance, ice-capable fleets, and northern runways.
Each item reduces single points of failure. Each one also costs money and time. The payoff is a force that can fight and sustain operations without last-minute U.S. lifts, stockpiles, or targeting data.
Risks and Possible Futures
There are different views on how far to go. Some officials argue the United States will remain committed, citing bipartisan support for NATO in Congress and U.S. interests in European stability. Others warn that political swings could slow or halt U.S. support at critical moments.
History suggests hedging is prudent. Europe’s share of security has grown before during U.S. drawdowns, then receded. The difference today is Russia’s active war, volatile energy markets, and the global pull on U.S. forces in the Indo-Pacific. That mix makes reliance riskier.
Shirreff’s core claim is simple: treat the alliance as if the safety net might loosen. Investing now would make NATO stronger even if U.S. support stays firm. If it does not, Europe and Canada will be glad they prepared.
The next months will show whether budgets become binding contracts, factories add shifts, and joint units reach higher readiness. Watch for durable spending laws, shared procurement deals, and new air defense sites coming online. Those markers will reveal if talk has turned into staying power.
