We (the US) has something the rest of the world cannot afford: true Stealth technology.  Everything our military does now and the future will revolve around it.  Sure the Su-27 has vectored thrust etc. and the Euro-fighter is very nimble.  The F-22 and JSF are that PLUS they are invisible.  Anyway-in 15 yrs you will still be flying the Euro-fighter and fighting with France about the name of the next Euro-program ;we will  be flying unmanned, supersonic, stealth drones.  Prototypes are already flying right now.  Thank God we don’t have to work with the French!!!!!!!!!!!!!!!!!!!!
