Clausowitz deals with land warfare. A better reference is Hughes "Fleet Tactics and Coastal Combat" which deals with Naval warfare. In space you have an "attrition environment" so the proper policy is to apply "effective firepower first". Unfortunately even Naval tactics won't be effective as there may be no available opponent. The easiest way to destroy a space object would be to hit it with marbles. The kinetic energy of a depleted uranium marble attack would likely penetrate almost any defense, including Whipple shields. A cloud of marbles would be hard to avoid. Of course, once the attack occurs the resulting space junk will likely cause a Kessler cascade (https://en.wikipedia.org/wiki/Kessler_syndrome https://en.wikipedia.org/wiki/Kessler_syndrome) and end up destroying everyone's assets. The future of war in space is maintaining the peace.
