quite simply "no"- copies of the "raptor" will sooner or later end up stripped down ( by China or Russia )anyway- so why sell it and allow for cheap copy cats to be made- the Mig 29s ,SU-27s and SU-30s are still a preoblem , and good old U.S. tech- though only a few steps ahead, is none the less ahead and should stay that way !The allies- are happy with block 40/50 F-16s as well as the F/A 18C/Es,the improved F-15D-Ls ,and the UK, Germany,and France have the choice of Rafales or the Euro fighter,as well as some good stuff coming out of SAAB,so why even the feild- the F-15 and its smaller sibling,the f-16 ruled the roost for at least 20 yrs,and the U.S hasn't had a capable dog fighter since the P-51 and the F-86( the F-4 phantom was the American equivalent to a suped up grocery getter and its far superior replacement ,the F-14,has been kicked to the curb for the sake of modern $$ spending!).I say ,we build a better killing machine and let the rest catch up................
