UAVs are here to stay..no doubt. I go with Tropic and Christopher Robins reasoning. Never say never!
A Global Hawk recently flew from California to Queensland Australia, the first USAF UCAV Squadron formed (with no pilots!)and the CIA are throwing more loot at I-Gnat, than David Beckhams account can hold. Control the technology, before it controls you!!
Forget your bandwidth mularky..we are all missing the most important factor...UAV design, doctrine and employment might be irrational..but we are led by irrational politicians..who just happen to be pig sick at doshing out FRIs to irrational pilots!
