Top military officials from the North Atlantic Treaty Organization (NATO) are warning of the possibility of a full-scale war with Russia within the next 20 years, urging the alliance and its civilian populations to prepare. This comes amid Russia’s ongoing invasion of Ukraine and shifting global power dynamics.
Military Chief Cites “Tectonic Shift” in Global Power Structures
In an interview at the NATO Military Committee conference in Brussels this week, Admiral Rob Bauer, chair of NATO’s Military Committee, stated that there is potential for a large-scale conflict pitting Russia against NATO member states in the coming decades.
“What we are seeing now is a shift, or an acceleration, of the tectonic plates of global power into a new reality,” Adm. Bauer stated. “So for me, the crisis, the war in Ukraine, is proving to be a curtain-raiser or catalyst for a much more fundamental shift.” 
The Dutch admiral pointed to Russia’s invasion of Ukraine, along with China’s increased assertiveness in the Indo-Pacific region, as signs of an emerging multipolar world order replacing the U.S.-led system of the last 30 years. He suggested NATO member states may need to commit more resources to defense spending and readiness.
“There is a real risk of some sort of systemic war, but not necessarily between the great powers,” Bauer said. However, he did not rule out the possibility of a direct NATO-Russia confrontation: “I don’t say it’s going to happen next week, but I think the trend is there.”
NATO Officials Urge Preparations for Potential “All-Out War”
Echoing Adm. Bauer’s remarks, NATO Deputy Secretary General Mircea Geoana stated that member state civilian populations should begin making preparations for a potential war with Russia within the next 20 years.
“In the next 20 years, we may well be involved in some sort of armed conflict with Russia,” Geoana told an event organized by the Clingendael Institute in The Hague this week. “Not the February 24 type of limited business — but all-out war.” 
Geoana clarified that he was not saying such a conflict is guaranteed to happen, but that based on recent geopolitical shifts NATO member states should bolster their defenses in preparation.
In addition, Vice Admiral Janusz Zembaczuk, head of NATO’s Allied Maritime Command, told journalists that the alliance must “expect the unexpected” when it comes to potential future conflict. 
Ukraine War Spurs Discussion on NATO Transformation
The stark warnings from NATO leadership come as the alliance convenes its Military Committee conference along with a meeting of the NATO-Ukraine Commission in Brussels. Russia’s invasion of Ukraine 11 months ago has prompted urgent discussion within NATO on modernizing alliance capabilities and strategy.
All 30 NATO member states agreed last year to radically increase defense spending in response to altered threat perceptions following Moscow’s assault on Ukraine. Several key member states, including Germany, announced historic boosts in military budgets. 
At this week’s Brussels summit, military leaders discussed integrating innovative technologies into NATO forces and synchronizing member state efforts to aid Ukraine’s military. Officials emphasized that the alliance must adapt quickly to address rapidly evolving security challenges.
“We need a warfare development command,” asserted Adm. Bauer. “We need to align our capabilities to be able, if necessary, to conduct joint close combat operations.” 
Adm. Bauer added that NATO should establish a training mission in Ukraine following the war to help modernize the Ukrainian military.
Escalating Tensions Over Ukraine Raise Specter of Broader Conflict
NATO’s stark warnings of potential open conflict with nuclear-armed Russia come as the war in Ukraine continues to escalate entering its second year. Intense fighting is raging in eastern Ukraine around the city of Bakhmut and nearby Soledar.
On Wednesday, Ukraine’s presidential office stated that at least 11 civilians were killed and a further 11 wounded in 24 hours of Russian shelling across eastern and southern Ukraine.  Russia has also unleashed successive waves of Iranian-made suicide drones and missiles on Ukraine’s energy infrastructure in recent months, leaving millions without heating or power.
While direct NATO intervention remains unlikely, the U.S. and European allies have provided tens of billions of dollars in military aid to Ukraine as the country fights for its survival. Advanced Western weapons and intelligence support have been credited with helping Ukraine slow and repel Russian offensives.
With the Ukraine war descending into a bloody quagmire, NATO leaders fear the Kremlin may resort to more reckless aggression if faced with the prospect of defeat. German Defense Minister Boris Pistorius told local media that Russian President Vladimir Putin must not be allowed to win in Ukraine, warning that failure to stop him now would encourage further violence. 
As NATO bolsters its presence in Eastern Europe, the risk of accidental clashes or miscalculation sparking a wider conflagration cannot be excluded. Thus preparations by member state populations and civil authorities should commence, officials argue.
Outlook: Further NATO-Russia Tensions Expected
In the near term, direct conflict between NATO troops and Russia remains unlikely as both sides seek to avoid uncontrolled escalation. However, clashes between Russia and NATO member states may occur indirectly via proxies and advanced weapons systems.
As the Ukraine war continues to strain relations, future flashpoints could involve Russia-allied Belarus or breakaway regions in Moldova and Georgia. Meanwhile China looms as an equally formidable long-term challenger to NATO’s interests in the Pacific.
With the U.S.-led international system looking increasingly fragile, experts foresee a more volatile and dangerous era ahead. NATO officials are urging civilian readiness as the alliance implements its most significant strengthening and reorientation since the Cold War.

In summary, top NATO military officials are sending an unusually blunt warning for member state civilian populations to ready themselves for potential full-scale conflict with Russia within the next two decades. While stopping short of saying such a scenario is inevitable, they cite major geopolitical realignments currently underway as reason enough to prepare alliance defense capabilities and public resilience accordingly. With no end in sight for Russia’s assault on Ukraine as proxy clashes intensify, risks of miscalculation and uncontrolled escalation cannot be discounted. NATO leaders agree that the post-Cold War era of relative peace in Europe has decisively ended, heralding a new age of heightened dangers that warrant serious preparations by member states. Public vigilance, defense spending boosts, and military technology integration are now top priorities as the alliance braces for more turbulent times ahead in relations with nuclear rivals Russia and China.
