The level of damage to the Saudi Oil production facilities by a fleet of drones, augmented perhaps by some small missiles, demonstrates that in the modern world of regional and local confrontations, it is the tactical weapons which count. The vast carriers, the nuclear hunter killer subs, the nuclear weapons and other strategic systems are of very little use. Moreover the massive military superiority of countries like the United States can be neutralised by simple weapons in the hands of an insurgent military of quite limited resources. There is a lesson for the so called Global Britain here. Our security will depend on our tactical capility, not on our giant aircraft carriers with their billion dollar planes.
