It’s worth noting we are at the start of an arms race. It will iterate all over the place.

For example, smoke and chaff deploying drones would make defensive fire harder. Anti air can be either baited (and so depleted) or rushed. Lasers can be shielded against, at least for a time. Jamming can be countered with line of site communications.

In turn, each of these can be countered.

A key thing of note is that your solutions are heavy. Fine for defending a static target, but problematic when dealing with defending a mobile unit etc infantry of transports. In those situations an extremely rapid, focused highly dynamic response would be required. The obvious way to deploy those fast enough is to have them automated and airborne, aka a drone swarm.

I might be completely wrong, current drone warfare is akin to the invention of the smoothbore musket. How it will develop remains to be seen (for better or for worse).
