France is currently gripped by a severe heatwave, with half the nation under red alert and authorities imposing an alcohol ban at a major music festival. This is not merely a weather event; it is a strategic vulnerability. Extreme heat acts as a force multiplier for civil unrest, straining emergency services and critical infrastructure.
The alcohol ban, while a short-term measure, signals a breakdown in public order. Hostile actors could exploit this: cyber attacks on power grids become more effective when demand surges for cooling, and disinformation campaigns can amplify societal tensions. France's military readiness must account for climate-driven disruptions.
This is a red line in Europe's defence posture.
