The most alarming development in the fourth year of the war is Moscowโ€™s explicit return to nuclear brinkmanship.

Dmitry Medvedev, Deputy Chairman of Russiaโ€™s Security Council, declared that any transfer of nuclear technologies or capabilities from the United Kingdom or France to Ukraine would โ€œradically change the situation.โ€ He stressed there should beย โ€œno shadow of a doubtโ€ย that Russia would respond usingย any weapon at its disposal, including non-strategic (tactical) nuclear arms.

This rhetoric was reinforced at the United Nations by Vassily Nebenzia, who accused London and Paris of covertly exploring โ€œdirty bombโ€ components and even French TN75 warheads for Kyiv โ€” claims firmly dismissed by Western governments as disinformation.

Meanwhile, President Vladimir Putin has labeled nuclear modernization an โ€œabsolute priority,โ€ especially after the erosion of arms-control frameworks with Washington. Russia continues to emphasize itsย nuclear triadย โ€” land-based missiles, submarine-launched ballistic missiles, and strategic bombers โ€” while reportedly reinforcing deployments in Belarus and near NATO borders.

The message is clear: Moscow is signaling that the conflict is approaching thresholds where deterrence doctrine could shift from declaratory to operational.

Moscow frames NATO expansion as theย root causeย of the war. According to Russian officials, Ukraineโ€™s pursuit of NATO membership violated the neutrality foundations established when Kyiv surrendered its nuclear arsenal under the 1994 Budapest Memorandum.

Kyiv, in contrast, argues that Russia fundamentally breached that memorandum by invading in 2014 and again in 2022.

In recent briefings, Moscow has stated that no peace settlement is possible unless:

โ€ข NATO expansion is halted.
โ€ข Ukraine returns to neutral, non-aligned status.
โ€ข Russiaโ€™s territorial claims over Crimea and four annexed regions are recognized.

This position has hardened even as diplomatic backchannels reportedly continue through intermediaries.

Energy has once again become a frontline instrument.

Theย Druzhba (โ€œFriendshipโ€) pipeline, one of Europeโ€™s oldest energy arteries, has become central to a dramatic dispute. Hungary and Slovakia rely heavily on Russian crude delivered via this route.

When oil transit through Ukrainian territory was suspended โ€” Kyiv citing Russian drone damage, Budapest and Bratislava alleging political leverage โ€” the fallout was immediate.

Viktor Orbรกn vetoed a โ‚ฌ90 billion EU aid package to Ukraine and blocked further sanctions, calling the oil stoppage โ€œopen political blackmail.โ€ Hungary also halted diesel exports to Ukraine in retaliation.

Robert Fico declared a state of oil emergency and suspended emergency electricity supplies to Ukraine, describing it as a โ€œreciprocal step.โ€

In response, leaders like Donald Tusk accused Budapest of โ€œpolitical sabotage,โ€ while Nordic states pressed Brussels to consider escalating Article 7 proceedings โ€” the EUโ€™s so-called โ€œnuclear optionโ€ โ€” against Hungary.

Europeโ€™s unity, once considered resilient, now shows visible fractures.

On the fourth anniversary of the invasion, the United Kingdom unveiled its largest sanctions package since 2022.

Targets include:

โ€ข Pipeline operator Transneft
โ€ข 175 companies tied to a โ€œshadow fleetโ€ oil network
โ€ข 48 tankers circumventing price caps
โ€ข Russian LNG terminals and banking entities

British officials argue that sanctions have deprived Moscow of hundreds of billions in revenue, although Russia has adapted through rerouted exports and non-Western markets.

This sanctions escalation runs parallel to the intensifying battlefield strikes โ€” including Ukrainian long-range drone attacks reportedly reaching deep into Tatarstan, striking facilities linked to the Druzhba export system.

President Volodymyr Zelensky released a cinematic anniversary address revisiting the first days of the invasion.

He reminded audiences of his now-iconic line:ย โ€œI need weapons, not a taxi.โ€

The message was strategic:

โ€ข Ukraine now produces millions of FPV drones annually.
โ€ข Advanced Western systems like Patriot and IRIS-T are operational.
โ€ข Statehood has survived despite relentless attacks on energy infrastructure.

Zelensky frames resilience as proof of sovereignty โ€” signaling that peace must come with security guarantees, not capitulation.

We are witnessing three simultaneous escalations:

โ€ข Nuclear Rhetoric Escalation
Tactical nuclear weapons are openly referenced.

โ€ข Energy Infrastructure Warfare
Pipelines, refineries, and grids are now strategic targets.

โ€ข Political Fragmentation within the EU
Aid packages and sanctions face internal vetoes.

Russiaโ€™s doctrine suggests tactical nuclear use only under existential threat. However, repeated public invocation of such options lowers psychological thresholds and increases miscalculation risks.

At the same time, Europeโ€™s energy disputes risk undermining long-term strategic cohesion.

Orbรกn posed the question bluntly:ย How can a nuclear power be defeated?

History shows nuclear states avoid direct existential defeat by escalating deterrence signals. The danger lies not necessarily in deliberate use, but in:

โ€ข Misinterpretation of intent
โ€ข Accidental escalation
โ€ข Political brinkmanship during domestic election cycles

With approximately 12,000 nuclear warheads globally โ€” nearly 90% controlled by Washington and Moscow โ€” strategic stability remains fragile.

๐‘พ๐’‰๐’‚๐’• ๐‘ช๐’๐’Ž๐’†๐’” ๐‘ต๐’†๐’™๐’•?

Several scenarios emerge:

โ€ข Managed Escalation:ย Continued conventional warfare with nuclear rhetoric as deterrence theater.

โ€ข Energy Fragmentation:ย EU divisions deepen, weakening unified sanctions policy.

โ€ข Negotiated Freeze:ย A ceasefire without final settlement, freezing territorial lines.

โ€ข Escalatory Shock:ย A tactical nuclear demonstration or major strike on critical infrastructure triggering direct NATO involvement.

The fourth year marks a psychological inflection point. The war has evolved from tanks and trenches into a multidimensional confrontation involving nuclear doctrine, energy leverage, economic warfare, and political cohesion.

The world now stands at a delicate equilibrium โ€” where deterrence must hold, diplomacy must revive, and strategic miscalculation must be avoided at all costs.
