Today? Nobody. In 2003? Iraq....and shitting on the Iraqi military with overwhelming air power made the ground war 10x easier...demonstrated twice. In less than 10 years, we quite possibly could be in an air war with China over Taiwan. We can't tear down and stand up military hardware like AWS VMs. The lead times for a viable, robust capability are sadly on the order of 2 decades. For China I'd argue it's maybe half of that... Our procurement process is screwed, and I'm not convinced most of it can be chalked up to "modern tech is complex".
