Leaders may recognize that they are not addressing the real problems, but they rationalize their actions with the argument that they must first politically survive in order to later address the hard problems and sacrifices. Of course, they usually don't ever actually get around to addressing the fundamental problems later, either because they don't make it through the initial crisis or because, even later, they are not willing to risk sacrificing their own position or "career" with needed measures that usually require tough sacrifices by the population.
