I recently returned from Ukraine, where I met officials, military personnel, and civilians living through one of the defining conflicts of our time. What I saw there was not simply a country at war; it was a nation determined to survive.
For Ukraine, this war did not begin in 2022. Russia’s aggression stretches back more than a decade, beginning with the seizure of Crimea and the conflict in the Donbas. However, the full-scale invasion four years ago transformed the struggle into something existential. Ukrainians describe it in unvarnished terms. This is not merely a dispute over territory; it is a fight over whether their nation will endure at all, and whether their children will inherit a country that is free to determine its own future. Russia’s campaign has been brutal. This winter, repeated attacks on energy infrastructure have left communities suffering long power cuts in freezing temperatures, leaving them without heat or light. Alongside the missiles and drones is an enormous disinformation campaign designed to break Ukrainian morale. Yet despite the inevitable fatigue and the human cost of war, the population remains remarkably resolute.
In many ways, Ukraine today bears resemblance to the biblical story of David and Goliath. A smaller nation, facing a larger and better-resourced adversary, has survived through ingenuity, courage, and resilience.
Nowhere is that clearer than on the battlefield.
Ukraine has transformed the character of modern warfare. Instead of relying solely on large, manpower-intensive formations, Ukrainian forces have developed sophisticated drone capabilities to blunt Russian mass attacks. Along parts of the front line, drones dominate the battlespace, creating “kill zones” where troops and vehicles simply cannot operate in the open.
This innovation has created a dynamic and highly competitive ecosystem, with hundreds of companies producing and adapting drone technologies at a remarkable speed. The result is a constantly evolving battlefield advantage that allows Ukraine to hold back a numerically superior force.
There are clear lessons here for Britain and our allies. The future of deterrence will not be determined solely by the size of armies, but by the agility and technological sophistication of our forces. Ukraine is already offering to share its experience with NATO partners, enabling allied countries to develop similar capabilities.
However, we must be clear-eyed. Military innovation alone will not end the war.
Russia continues to finance its aggression through energy revenues, often transported by the “shadow fleet” of tankers operating outside international regulations. If we are serious about supporting Ukraine, Western sanctions must become far more robust, targeting not only the vessels themselves but the insurers, ports, and financial systems that enable them.
Ultimately, ending the war is predicated upon Russia no longer being able to sustain it.
Ukraine’s people understand that reality. Many believe the conflict could continue for several more years. Yet they remain determined, not because they desire war, but because they understand the consequences of losing it.
For Britain, the message is clear. Ukraine’s resilience is extraordinary, but it cannot stand alone. In the months ahead, we must draw the lessons of this conflict about technology, sanctions, security, and European defence and ensure that the free world responds with the seriousness this moment demands.
Ukraine is fighting for its survival. In doing so, it is also defending the principles that underpin our own security.
