A criticism of Frankfurt-counterexamples presented by David Widerker and known as the W-defense has been resilient for years and has been considered one of the strongest challenges these counterexamples have to face. In this paper I offer a defense of Frankfurt counterexamples from Widerker's attack by presenting a dilemma for the Principle of Alternative Expectations, it's main premise: either on the one hand, this principle rests on the Kantian maxim ought implies can, which makes the principle, and Widerker's whole argument, redundant and unnecessary; or the principle does not rest on such maxim, but then there is no good reason to accept it as valid
