The article delves into the evolution of warfare from traditional means measured by physical assets like tanks and soldiers to modern cyber wars, where the most devastating weapons are composed of ones and zeros. It highlights how today's conflicts are fought in a digital arena that has become as significant as land, sea, air, and space, as recognized by NATO. The implications of this transformation challenge the concept of sovereignty, as the barriers of accountability blur due to the complex nature of cyber attacks, making it difficult to legally prove state-sponsored acts of aggression.

Moreover, the piece emphasizes that cyber warfare represents a smoke-free arena where a single line of code can enact greater destruction than a conventional airstrike, such as plunging entire continents into darkness. The risks associated with cyber conflicts are underlined by the potential to attack critical infrastructures like energy and water supplies without clear attribution, an issue defined as 'plausible deniability' in military strategy.

Finally, the article laments the vulnerability of national infrastructures that serve as a country’s nervous system. It underscores that in cyber wars, such infrastructures are being targeted across three main fronts—energy systems, water systems, and critical communication networks—each crucial for maintaining societal functions and security in the modern world.
