It might only seem like a minor detail to many, but I could suggest one way to give allied nations a good deal more punch to deter a potential Chinese invasion while bringing in a little cash and boosting relations with those allies at the same time. Even though it might initially cost a bit more, I'd ramp up the current production of F-22s and F/A-18 E/Fs and the planned JSF production by 144 (2 wings) or 216 (3 wings) each. Then I'd sell off some of the USAF's currently-flying F-15s (mostly C models, maybe a few E's) and F-16s, and a bunch of older Navy F-14s and first-generation F-18s to Taiwan and South Korea. (Japan and Israel have licensing to build their own versions of the F-15 and F-16 already.) That'd leave all Air National Guard aircraft in place (which would still be available in the event of full-scale war), it'd give the USAF, Navy, and Marines that many more advanced aircraft for which there isn't any real counter anywhere, and most importantly, it would bolster allied air forces tremendously. The Chinese air force isn't anything to sneeze at, with the best Russian jets currently available and a number of well-trained pilots, but a combination of more American hardware and more aid with tactics and training would definitely give Taiwan and South Korea a hell of a deterrent force. To keep relations and force readiness up, there could be more multinational exercises that would help pilots from all those countries stay sharp. Superior air power is a good way to stall just about any enemy invasion.
