And do not sell the Raptor to ANYBODY other than US forces.
There's a good case to be made for allowing Japanese co-production and Australian purchases. The Japanese need a replacement/augmentation of their F-15J's, and the Aussies have been waiting quietly for 10 years for us to get our poop in a group on the F-35, and we've failed to come through for them.
Other countries have options like the Eurofighter Typhoon and the navalized Rafale and F/A-18 and can get by without the F-35, but if you look at Japan and Australia's situation, you see the need there.
If the F-35 project does go down, it'll be our biggest program failure since .... well, ever. The Pogo failed, the Flying Wing failed, the predecessor of the Osprey failed in the 60's, and of course the XB-70 failed. But this will be the worst, if it does fail.
I wish I knew what was adding all the cost. I am not sure the people urging the program's termination have our best interests at heart, however. This article examines the interests vested in carrying the program forward -- well, how about a list of companies, governments, and NGO's vested in the other side of the question?
