It is unlikely that the rising pressure on the world economy will allow oil hungry and developing nations to last till starvation takes us all from Global Warming.  The need to take oil by force will push the world leaders into manufacturing reasons to attack and occupy oil rich nations of lesser military power.
The retaliation of the oppressed peoples of these conquered nations will be left with no options but to attack in the most sacrificial methods at their disposal.  Nuclear suicide bombing will strike the heart of large cities like New York and Seattle before it’s over.

I guess thats started already with the Iraq situation.

Cliche time:

what goes up must come down

the bigger they are, the harder they fall

USA = Rome most definitely.
I've been comparing Bush to a Roman Emperor for a long time (given how he came into power and rules).

So so so so sad ... March 15 is Bush's deserved day.

What comes after? I hope we don't all burn.  

There is an interesting History Channel documentary on the "when oil runs out" or something similar.  There was another one on "oil" which also discussed the diminishing supply.  It did discuss the possibility of global conflict over oil.  They did not bring up nuclear as a means.
What they did bring up the Mad Max Road Warrior scenario.
I am not sure what the outcome will be, but believe it will be good for our children's, children.

Be well . . .

Is this a prediction based on the mystical or a prediction based on the world we see on the evening news?   Does NOT seem to be very mystical, if you ask me.  

Also, global warming is not going to end the world.  We are entering the next ice age folks...prepare for THAT.
