According to a National Review article "The F-35 program is a mess; it is unaffordable and will not be able to fulfill its mission. Indeed, it could be argued that the biggest threat the U.S. military faces over the next few decades is not the carrier-killing Chinese anti-ship ballistic missile, or the proliferation of inexpensive quiet diesel-electric attack subs, or even Chinese and Russian anti-satellite programs. The biggest threat comes from the F-35 — a plane that is being projected to suck up 1.5 trillion precious defense dollars. For this trillion-dollar-plus investment we get a plane far slower than a 1970s F-14 Tomcat, a plane with less than half the range of a 40-year-old A-6 Intruder, a plane whose sustained-turn performance is that of a 1960s F-4 Phantom, and a plane that had its head handed to it by an F-16 during a recent dogfight competition. The problem is not just hundreds of billions of dollars being wasted on the F-35; it is also about not having that money to spend on programs that would give us a far bigger bang for the buck."

But an article in Forbes informs us that "Summer is the silly season for defense coverage in the nation’s capital" and that "journalists have to work harder to find anything worth reporting. When they uncover an item that sounds like it might be newsy, they get as much mileage out of it as they can." for example, a story breaks about the new F-35 losing a dogfight to an F-16, and a plethora of articles on the Joint Strike Fighters follow. "The F-35 fighter is an easy target because its budget dwarfs funding for other programs, and the plane thus is a lightning rod for every conspiracy theorist’s fears about the machinations of the military-industrial complex. Few of the reporters on the defense beat realize that all of the legacy fighters sustaining America’s global air power today were subjected to the same sort of withering scrutiny during their own development." Running against the trend, this article gives ten reasons why the F-35 is a smashing success.
