I was talking about this with a friend and my partner recently. A war with the US involved would not look like this. Drones are not omnipotent nor are they immune from physical reality. Extensive use of drone warfare to the level of the Russia-Ukraine conflict is an artifact of limited personnel, poorly-developed anti-drone defenses (including EW) and lack of funding for superior non-drone resources.
That is, drones are in use so heavily there because it is the best of a lot of bad options. Other players like the United States and China have superior options so any war with major well-resourced nations would not at all look like the Russia-Ukraine War. People really do have trouble contextualizing events and the vicissitudes of fate and circumstance and don’t seem to realize that what’s occurring in Ukraine will not be how war would look everywhere for every combatant.
Note that I am not saying that drones would not be used in, for example, a US-China war. They absolutely would, and heavily. They are now an unavoidable feature of modern warfare. However, the US already has better anti-drone defenses than Ukraine is ever to likely lay hands on. Those are also improving all the time.
Another point: Drones are very large targets on radar, very slow1, and not that powerful. In other words, they are quite easy to shoot down with the appropriate technology. A drone is just a cheap, slow missile, and the US is actually quite good at dealing with those.
Drones appear all-powerful because Russia and Ukraine use them by necessity and have poor counter-drone defenses. That will not be true of every conflict and is very specific to the circumstances of a single war.
