This includes $45.6 billion for military aircraft, including $6.7 billion to buy 16 more F-35 stealth planes. The F-35 is still in its early stages; the Pentagon has, to date, spent only about one-tenth of what it estimates to be a $300 billion program. It's not too late to ask if we need such a costly, sophisticated fighter jet, given that air-to-air combat is not likely to be a major element of future wars and, to the extent that it might be, we're way ahead—in numbers and technology—of any prospective foe. Or let's accept the proposition that China's air force is going to be a formidable rival by the year 2020: Do we need to tear full-speed ahead on the F-35 now? Could we slow the program down and see how things shape up?
