I'm in awe of your expertise and personal knowledge of these aircraft.
Unless of course you're just parroting some crap someone else has come up with, because lets face it, pretty much every new system in the part 50 years has been a called a dud (or similar) at some point during it's development. I said earlier there are risks, but, unlike you, I'd rather see proof before I write things off.
As for drones...sure, for air-ground strikes, they're fine, but where are the air superiority drones, without which the ground strike craft would be wiped out? Sure, in time they'll be developed (they're on the way already), but if you use the same criteria for assessment, current AS drones are 'duds'.
Thats the point. Why not buy specialised air superiority fighters that are not comprimised 'jack of trades' and leave ground strikes and recon work to drones?
