The nature of war has always mirrored the anxieties of its age. In the Cold War, fear was defined by the mushroom cloud, and power was measured in missile silos.Still, the confrontation had never reached the point of open conflict; rather, it played out in murkier tributaries, such as espionage, proxy combat, and propaganda. Citizens also came to understand that cultural domination could be exerted without the need to pull a trigger.
That era institutionalised the idea of the arms race: a self-perpetuating competition between great powers, each trying to outpace the other in capability rather than conversation. Deterrence rested not on trust but fear of retaliation. The need to accumulate in itself became doctrine, with states racing to escape the impending catastrophe.Today, the domain has changed. We are no longer racing for physical firepower, but for cyber dominance. This is not a battle doesn’t rely on brawn or the race of who can build the bigger, scarier bomb, but of who can infiltrate deeper, disrupt longer, deceive better. The cyber arms race is not a reflection of Cold War doctrine, but a deviation from it making it unregulated, decentralized, and heavily asymmetrical.
Where once we feared missile launches, we now fear breaches in network. In the digital theatre, conflict isn’t something that gets declared but is persistent. Malware slips through backdoors, zero-day exploits are hoarded like tactical secrets, and the actors range from government entities to ideologically motivated collectives. What perturbs us is not just how frequently these activities occur, but the complete and utter absence of consequence for it. This is because there is no standard of response, no definitive line between provocation and war.The theft of F-35 data, the Stuxnet operation, the persistent targeting of Ukraine’s infrastructure are each examples that unveil a totally different face of cyber aggression. None of these operations directly provoked a kinetic war, but somehow always revise strategical placement. They forced governments to assess and understand how invisible aggression should be countered, especially when attribution is murky.
In the absence of norms, escalation becomes convenient. It is not marked by military deployment or aircrafts, but by subtle manipulations: the undermining of trust in public institutions, the degradation of electoral systems, the corrosion of critical infrastructure. And unlike the Cold War, where the balance of terror was mutually visible, cyber conflict is ‘fought’ entirely behind a veil called the screen. The very act of exposure often occurs far too late for any structural rebuilding.Unlike nuclear weapons, cyber weapons are finite in effect and unstable in value. Their power diminishes with each use. Once a vulnerability is revealed, it is patched. This undermines the logic of deterrence. One cannot threaten with a decaying arsenal. One must attack first, fast, and in silence.
State actors, of course, remain central, especially states like the United States, China, Russia, Iran, and North Korea among them – but the theatre is now crowded. 3rd parties like Hacktivists, cyber criminals, private contractors, and unaffiliated groups blur the strategic map. Sovereignty, in this space, is porous. The battlefield is often a corporation, a utility grid, or a hospital. Civilians are not watching from the sidelines but are now the target.
Information warfare completes the picture. Not just the manipulation of facts, but the planting of doubt. Troll farms, disinformation campaigns, and manipulated social media echo chambers degrade a society’s ability to discern what is real and when they are being fed misinformation. When belief itself is destabilised, so too is the people and society that relies on it.
The implications of such a war is not concerning from just a strategic point of view but from a very primal moral stance too. Who is a combatant in a world where malware can be written by a contractor in one state and deployed in another, under orders from a third? What protections exist for those who host data without knowing it holds strategic value? Where is the Geneva Convention for servers?
Efforts from global governing structures remain tentative. Existing treaties have limited reach, and definitions are contested. States need to stop relying on overarching structures and take self-preservation gravely. VA Greiman observed, the lack of legal consensus leaves responses to cyber incidents inconsistent, politicised, and ultimately ineffective.
The future of deterrence may depend less on retaliation and more on resilience. Not merely preventing breaches, but ensuring that breaches do not break the system. This means building infrastructure that bends without shattering, investing in early detection, and accepting that some level of infiltration is inevitable.
What looms is not a war in the traditional sense, but a corrosion - of stability, of norms, of trust. The next world war may not be declared at all. It may unfold slowly, subtly, line by line, packet by packet, until one day we realise it has already begun.
