Potent but not invincible. As I say they haven't met the real match yet. Times flies. Empire will decline. New one will rise. The world do not always revolve just on one nation. Until now, USAF still do not have a true 360 degress AESA AWACS. The most a PESA 360 degrees E2-D APY-9 Radar. Becos US could not solve the problem of AESA 360 degrees AWACS cover.This is flawed argument, and reasoning.
USAF bring lot of assets to bear for aerial engagements, and throws potential adversary in disarray. American electronic warfare equipment is very potent in particular.
Iraqi Air Force was very good in 1991.
While China has long solve the cover problem for an AESA 360 degrees AWACS with KJ-2000.
More than a dozen of newest KJ-500 AESA 360 degrees has enter service for PLAAF/PLANAF.
