Why not since everyone know that already. Ukraine war proven that not as much changed in the peer warfare since WW2 as Usians would like when they focused their military on imperializing much weaker states by the aerial warfare, but the mass drone usage is pretty much already acknowledged as the biggest change that came out of that war. And US analysts are probably burned by this since US previously concentrated on big and expensive drones being essentially unmanned planes, like the Reaper for example.

But they do have reasonable hope of this particular tool of warfare to turn to their favour since US is after all pioneer in aerial electronics. What they missed though is one key factor that makes that mass drone warfare effective, it the “mass” keyword, Ukraine, Russia and countries paying attention like Iran all are manufacturing those drones pretty cheap compared to their usefulness, but US MIC will never be able to do that. I mean sure they will make a lot of drones, but not nearly enough and every one of them will be overengineered and also US military will pay for it the usual multiple price.
