It's not that they don't answer the questions of today. They don't address those questions. They weren't meant to.
The Nixon Thesis of Conflict holds that we must hold "them" in check to save the nation. In terms of foreign policy, them meant Communists. Russian Communists. Chinese Communists. In the context of the time, Vietnamese Communists. Vietnam was a Cold War activity, and the Nixon Thesis was designed, first and foremost, to support the Cold War. It made that war the nation's partisan divide, with the dominant side supporting it without question. With 9-11 the enemy simply changed -- the 1990s represented the Thesis' search for this new enemy.
Domestically the Nixon Thesis of Conflict also opposed "them" -- represented by any force which questioned societal norms in dress, demeanor, values or lifestyle. Initially this referred to the Dirty Fucking Hippies and their enablers in the academies and the media. Gradually, as that threat receded, new groups were thrown off the majority coalition -- first feminists, then blacks, then gays, then browns. Those who protested at the exclusion of these interests were also tossed overboard, and the full weight of societal scorn heaped upon them.
