# NATO's deterrence 'weakened' by lack of response to Russian attacks

## Executive Summary
European security concerns mount as NATO's deterrence capabilities are questioned amidst Russian hybrid attacks that fall short of open warfare.

## Intelligence Brief
Current reporting indicates that Europe is struggling to formulate an effective counter-strategy against Russian attacks that do not meet the traditional threshold of war. The core issue center on how the North Atlantic Treaty Organization (NATO) maintains deterrence when faced with hybrid threats that deliberately avoid triggering a full-scale military response. This strategic gap has led to concerns that the alliance's overall deterrence posture has been weakened by a lack of decisive reaction to these specific types of incursions. The reporting focuses on the difficulty of identifying the exact point where persistent hybrid activities transition into a state of actual conflict.


Simultaneously, ARTE Europe Weekly is examining the conceptual boundary of this struggle, specifically questioning when a hybrid war officially becomes a real war. Both outlets highlight a shared anxiety regarding the current inability of European powers to provide a deterrent effect against tactics that are designed to destabilize without initiating a conventional military confrontation. The context surrounding this trend involves the evolution of Russian tactics, which utilize hybrid warfare to achieve strategic goals while remaining below the threshold that would mandate a collective NATO response. This environment creates a paradox where the alliance is designed for large-scale deterrence but finds itself ill-equipped for persistent, low-level aggression.


The stakes involve the potential erosion of NATO's credibility, as the failure to respond to these attacks may signal a vulnerability in the alliance's commitment to defending its members from non-traditional threats that still cause significant damage. Future developments to watch include how European nations and NATO leadership define the transition from hybrid warfare to conventional war. Observers will be looking for specific shifts in how the alliance categorizes Russian aggression and whether new mechanisms are introduced to provide a response to activities that currently fall short of the trigger for a general military engagement.
