"Sub-orbital and orbital fighters can fly right over the F-22 with impunity already today."
Ok, assuming these mythical orbital/suborbital fighters even existed, sub-orbital/orbital offers little, if any tactical advantage. Speed and altitude are only valuable if you can do something with them. You can't maneuver in suborbital/orbital flight, save reaction motors....more cost, weight, less payload....which will be plenty small for an aircraft with this flight profile, even if it did exist.
F-22 is real - albeit expensive as hell - and has some useful capabilities, it isn't magic, but it ain't bad either.
Nonsense. ...And both of your above claims are already dealt with in posts #145 and #146.
