Fifth-generation warfare: a conflict with no front lines

«We are at war. We are the weapons and, at the same time, the victims. And all of that without firing a single shot». The line could open a dystopian novel, but it sums up a strand of military analysis gaining ground in recent years: so-called fifth-generation warfare (5GW), a conflict where the battlefield is not the trenches but the narrative, the economy and social cohesion.

The theory, drawing on sources such as Daniel H. Abbott's handbook, traces the evolution of warfare from Napoleonic formations to the manipulation of public opinion. In this scheme, the first generation uses firearms and professional armies; the second, large mechanised forces and trenches. But the fifth no longer needs kabooms: its main weapon is control of the story.

Why is everyone suddenly talking about a war that is never declared?

The turning point, according to these analyses, came in the 1990s: the Gulf wars (1990-91) and Yugoslavia (1991...) marked the shift to conflicts where information and public perception weigh as much as bombing. Whoever controls the narrative controls the decision. There is no need to lie brazenly; it is enough to steer the conversation and ridicule the dissenter.

The shift from conventional to unconventional warfare accelerated with the 2020 pandemic. Some interpretations go further: the lockdowns and the drop in energy consumption would have been a large-scale experiment in social control and preparation for the rollout of artificial intelligences. More sober readings simply point out that Western societies no longer need to be invaded: they are destabilised from within.

Is it war or isn't it?

Not everyone accepts the framework. The most direct objection is that a war without gunfire is not a war, but a metaphor for selling politics. If there are no armies facing each other, where is the conflict? The answer from 5GW advocates is that military theory already contemplates these phases: the enemy wears no uniform, but acts on demography, the economy and institutions.

Some argue that what we are seeing is not so much a war as a silent occupation. In Spain and much of Europe, the enemy would already have overrun the institutions: there is only one side, and the country fights no one because it is already subjugated. This view drifts into domestic political debate, with accusations flying over who benefits from the destabilisation.

The shadow of social engineering

The most controversial chapter of the analysis links 5GW to the management of migration flows and demographic change. The argument is that the mass importation of population and the promotion of regulatory chaos are deliberate tools to break the cohesion of nations. However, these claims run into a more complex reality: migration movements respond to multiple economic and geopolitical factors, and attributing them to a single conspiracy is, at the very least, reductionist.

What does seem beyond doubt is that disinformation and polarisation are weapons of everyday use. Fifth-generation warfare needs no fronts or flags: it is fought in every bar conversation, every trending topic and every vote. The unsettling fact is that, despite the scale of the phenomenon, there is no coordinated institutional response. Perhaps because, as one analysis notes, the frog doesn't jump when the water is heated slowly.
