The Japanese Stealth Fighter

Sweetman is arguing this is to ease concerns that the US would be exporting stealth technology with the purchase of the F-22. It might be the flip side to that the Japanese are saying they are going to design and build a stealth fighter anyways and have done their homework: think of it as an exercise in trade negotiations. The above could be made into a competitor for American fighter exports...causing some nontrivial issues. Esp for the F-35.
