If the present economic debacle snowballs into a worldwide depression, there is no doubt that we will see some despots arise in major nations.
POh I think it already is, OR, don't you?
And economic ruin and political depotism are old chums.
At the same time, we still have the ongoing global warming. An arms race, with no thought at to what we doing to ourselves could quickly excaberate the already shaky situation in regard to climate, and the agricultural resources that depend on stable climate. So we could well end up in a world with major portions of the population in a starvation situation, well armed nations, possibly nuclear, controlled by despots, and no organization or nation big enough to put the brakes on the situation. A very unpretty picture.
It would take about six months to starve half the world's population to death. Mostly they'll die of dieases related to malnutrition, of course, but the root source will be a lack of food and potable water.
Hell! they're living (in a market economy) on less than $2 a day, their governments are weak and/or oppressive.
And, should things get truly bad, things won't be exactly sweet here in America, either.
This is at least one reason I am somewhat sympathetic to those of you who cling to your guns and Bibles.
Be prepared!
