Science Fiction as Political Prognostication

This strays perilously close to putting a serious dent in my "no politics" rule, but over on Fraters Libertas Chad the Elder writes:

Today, I received an e-mail from Al Gore on behalf of MoveOn.org. In the midst of his plea for Obama volunteers was this gem:

But the stakes this year are too great for any of us to sit it out. We're facing two wars and an economic meltdown. The climate crisis, in particular, is worsening more quickly than predicted and without strong leadership from the next president, we could face consequences right out of a science fiction movie.

No one knows science fiction movies like Al Gore.

Perhaps so, but the all-important and thus far unasked question is: which science fiction movie? Silent Running? Soylent Green? Lord of the Flies? Godzilla vs The Smog Monster?

Personally, my money is on The Manchurian Candidate.

Your thoughts, s'il vous plait?
