What constituency is rooting for the end of the world?
The people who buy the books and follow the writings of:
people like Gerald Celente and others who sell books and go on overnight radio tallking about some coming apocalypse.
Among the beliefs is that all the Jews must return to the Holy Land, and there must be a great battle in the Holy Land for the apocalypse to occur. The people that believe this stuff exist. They are in my family, and I have met them at the shooting range. They are politically active, donate to candidates, and they vote. At the very least, a successful Republican primary candidate needs to be sure not to tick these people off.
Now, on the other hand, given our national debt, our spending, and everything, we very well could see a financial apocalypse in the near future if we can't get ahold of our out-of-control govt. spending. And that's no supernatural precogitation either, it is a very real threat to this country's future.
Sounds like a good reason to not waste our blood and treasure on numerous, undue foreign entanglements. It is also a good reason not to engage in "foreign aid" that is little more than corporate welfare for the Defense industry.
