How likely is it that a conflict between two combatants involving both kinetic and cyber operations would be an asymmetric one? And does the answer to that question depend on who the combatants are? In a kinetic scenario, the creation and “massing” of forces is often possible to observe. Whether it is the number of troops, warheads, or aircraft, one can physically monitor the activity. The buildup can be measured in days or weeks. Such a scenario involving state-of-the-art kinetic weaponry also needs a high level of expertise that only comes from years of education and training. One needs a well-funded organization to support this kind of activity.
You can trace the kinetic matériel fairly accurately to its source, and the effects of a kinetic attack unfold over an observable period of time. You can watch and react to it. Defense is possible as long as you are sufficiently diligent and prepared with a response.
