The concept of ‘hybrid warfare’ undermines NATO’s strategic thinking: insights from interviews with NATO officials
Open accessAbstract
Hybrid warfare has been a popular term that refers to contemporary warfare. Despite the increasing number of critiques, NATO has used the term in its strategic documents and summit declarations. Since concepts are important in shaping our understanding and the way that our forces fight, NATO’s use of a controversial concept has raised some questions. In this context, this paper aims to explore the meaning of the hybrid warfare from the viewpoint of NATO, based on in-depth interviews with NATO officials who have sufficient expertise and experience about the concept. The authors conclude that hybrid warfare is an ambiguous concept which clouds NATO’s strategic thinking and leads NATO to forget the difference between war and peace. Further analysis has revealed that NATO uses this concept as a tool for the strategic communication rather than a military concept.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
