The denser and more powerful the defensive shield along Russia’s borders becomes “here and now,” the less likely the Kremlin will be to risk a fatal gamble by invading Europe.
The geopolitical architecture of the Old World, built over decades around principles of de-escalation and demilitarization, has effectively disappeared. The direct and tangible threat of a large-scale Russian invasion deeper into Europe has forced NATO’s frontline states to act without delay. What was still considered a political taboo yesterday is becoming a hard military necessity today.
This means an accelerated revision of defense doctrines, the dismantling of pacifist legal restrictions, and the return of tactical nuclear weapons to the continent.
Lithuania’s initiative, in which President Gitanas Nausėda and parliamentary leaders reached a consensus that Article 137 of the Constitution — which prohibits foreign military bases and weapons of mass destruction — is outdated, is not an isolated development. It is a logical continuation of a broader military-strategic trend spreading across NATO’s eastern and northern flanks.
A nuclear “domino effect” stretching from Finland to Poland is already beginning to move Europe’s complex and traditionally slow-moving bureaucratic machinery.
Lithuania is effectively catching up with its neighbors by clearing the legal path for the deployment of allied deterrence capabilities. The countries already involved in this process include:
► Finland has set the pace by adopting legislation removing restrictions on the import, transit, and storage of nuclear components on its territory for defensive purposes.
► Poland is conducting high-level talks with Washington on integrating into the NATO Nuclear Sharing framework. Warsaw has made clear that it is prepared to host U.S. B61 tactical nuclear bombs.
► Norway, Sweden, and Denmark are simultaneously deepening cooperation with Paris and considering participation in a new defense initiative.
Removing legal restrictions is not merely a political gesture. It eliminates the so-called “grey zones” that the Kremlin has repeatedly sought to exploit. If an adversary knows that the deployment of nuclear-capable weapons on the territory of a particular state is prohibited by law, it can automatically factor that limitation into its military planning as a potential weakness in NATO’s defenses. Those assumptions are now being challenged.
The French factor deserves particular attention. France’s “Dissuasion Avancée” doctrine is changing the strategic equation. Finland is now considering the possibility of hosting not only U.S. but also French tactical nuclear capabilities. This is critical to understanding the future security architecture of the continent.
Historically, Europe’s nuclear umbrella has been associated almost exclusively with Washington. France, however, is the only EU member state with a fully sovereign nuclear arsenal that does not depend on decisions made in the White House or fluctuations in U.S. political cycles. Paris has recently formally articulated its “Dissuasion Avancée” doctrine.
Under this concept, Emmanuel Macron has announced not only the first increase in France’s nuclear warhead stockpile since the Cold War — to more than 370 warheads — but also a willingness to deploy aircraft from the air component of France’s nuclear triad to air bases operated by European allies.
The potential deployment of French air-launched ASMPA cruise missiles, carried by Rafale fighter aircraft, directly to Finland would fundamentally alter previous calculations by the Russian General Staff.
For Moscow, this would create a situation of profound strategic uncertainty. Russian commanders could no longer assume that any response to an attack on Scandinavia would depend exclusively on Washington’s approval. Paris is making it increasingly clear that France’s nuclear capability has a broader European dimension. A willingness to deploy French nuclear “retaliatory weapons” at Finnish bases would demonstrate that Europe is developing its own autonomous deterrence system, capable of responding immediately.
The main trigger behind the radical changes underway in Helsinki, Vilnius, and Warsaw is the growing recognition that Russia is preparing the infrastructure for a major war in Europe. Western intelligence communities have repeatedly warned that if an aggressor attempts to test the strength of Article 5 of the Washington Treaty, allies may have little time for deliberation or complex logistical preparations.
Russia’s strategy is built around the concept of fait accompli — rapidly seizing part of a territory, such as the Suwałki Gap or areas along the Baltic borders, and then using nuclear threats to prevent their liberation. This approach has been tested in Ukraine and could potentially be applied against the Baltic states in the future.
Under these circumstances, the deployment of operational-tactical missile systems and tactical nuclear weapons directly in the region would serve three critical purposes:
1. Maintaining strategic parity.
Russia has already transformed Belarus into a forward nuclear platform and militarized the Kaliningrad region, saturating both areas with Iskander-M missile systems. Leaving the Baltic region and Scandinavia without a comparable response would amount to creating an invitation for further aggression.
2. Reducing the reaction-time advantage.
The presence of precision operational-tactical missile systems directly on NATO’s first line of defense would undermine Russia’s advantage in response time. Moscow would have to recognize that any attempt to concentrate forces in the Bryansk, Pskov, or Leningrad regions for an attack on Europe could immediately place those forces within range of allied missile systems.
3. Direct battlefield deterrence.
Unlike strategic intercontinental ballistic missiles, which represent weapons of last resort, tactical nuclear weapons are designed to provide a more immediate deterrent against large-scale armored and combined-arms formations.
We are witnessing the final dismantling of the remnants of the Cold War-era security architecture and the pacifist assumptions of the 1990s. Europe no longer places its security on paper guarantees and diplomatic appeals alone. Against Moscow’s aggressive intentions, the language of power and the logic of credible deterrence are increasingly becoming the decisive factors.
Authorizing the potential deployment of operational-tactical missile capabilities and lifting restrictions on the stationing of nuclear weapons — both American and French — on NATO’s eastern flank should not be viewed simply as escalation. It is an attempt to create an effective defensive shield.
The denser and more powerful that shield becomes along Russia’s borders here and now, the less likely the Kremlin will be to risk a potentially catastrophic gamble by invading Europe.
The clock is ticking, and 2027 is approaching rapidly.
The question is whether Europe can build this shield in time.
