The DoD's plan is in place just in case another breed of zombies tries to takeover from the current zombies in office.
I’ve never really been a fan of zombie apocalypse movies and such. “Night of the Living Dead” was a midnight movie cult classic when I was in college, for the same reason as “The Rocky Horror Picture Show”: it was an excuse to get out of the dorm late at night, meet girls, make them squeal and get them drunk.
Medically speaking, the entire concept of a zombie is just freakin ridiculous at first glance. The brain deteriorates to the point of not functioning after ten minutes without oxygen. So the idea of shooting, bashing or stabbing a zombie in the head to destroy it — I refuse to say “kill,” since you can’t kill something that’s already dead — compounds the ridiculous nature of this. A zombie brain isn’t functioning in the first place, so it’s kind of like appealing to a Hollywood Democrat’s sense of decency.
The two most recent efforts in this genre, however, have been a pleasant surprise. “World War Z” posits a zombie virus that animates the corpse after ten seconds — which is certainly a timespan that’s brief enough to keep the brain alive. And “The Walking Dead” posits a zombie which is controlled from the brain stem, which can survive much longer than the rest of the brain without oxygen.
Both of these works exhibit real plots, quality character development and relationships among survivors, and group dynamics that were either pitiful or simply nonexistent in earlier shows, such as “Night of the Living Dead.”
Enough criticism of “the cinema” such as it is ... let’s take a look at the DoD plan. The zombie apocalypse idea is so far-fetched: even assuming that a WWZ or TWD type virus could develop or be developed, it would have to spread and the contagion would have to be rapid.
This is what leads me to believe that “zombie” might be a code word for something else.
