In the field of radio, while everyone was struggling with the application of technologies like radar, who would be crazy enough to think about how to interfere with such things?
Of course, the military of various countries had thought about ways to deceive each other's radar, but these methods were all still at the primitive stage of things like "throwing off chaff."
Countries around the world had not yet miniaturized radar and had no way to produce small radar units that could be mounted on aircraft... let alone work on so-called electronic warfare.
