I give this analogy because I believe it is very accurate.
I compare US energy demand to cancer.
Cancer has several stages.
But the last stage (#4) is called "Metastasis" and it's the last stage that spreads over the entire body and kills the very host that is giving it life, thus killing itself.
Metastasis is where cancer spreads, as if with tentacles, it reaches all over the body and invades and penetrate into lymphatic and blood vessels, circulate through the bloodstream, and making the situation terminal. At this point the adrenals, liver, brain and the bones are invaded.
The US economy has been using dollar hegemony coupled with foreign policy based on double standards and hypocrisy in order to reach far for such energy, literally energy from all corners of the planet.
The US economy will not change, it will not try to lower it's need of imported energy or imported finished goods. It will not happen in a purely voluntary method. The only way this change can be induced is when the entire planet plunges into a steep decline of peak oil. At this point the US economy will stutter, hopefully because of it's massive reliance on energy inefficiency in suburbia that it will suffer demand destruction first and strongest than the rest of the planet.
In the end, we can only hope that the cancer will die, not the entire body, not the other organs.
America needs energy, and she will kill Iraqi women and children to get it. She will pump NGO money into places like Venezuela, Ukraine, Georgia and around Chechnya because that energy belongs to America. Cancer doesn't negotiate, as Dick Cheney said "the American way of life isn't negotiable".
Ultimately we hope that economies and nations will consume only (mostly) renewable energy, and stop the exponential growth as Albert Bartlett pointed out.
Washington DC cabinet meeting, oval office meetings with the CIA, are going to be very creativity, with fantastic imagination and innovations in story telling and fairy tale engineering. You think "wmd in Iraq" or eluding that "Saddam did 9/11" was a stretch? Wait till the cancer starts to lose her metastasis, we ain't seen nothing yet.
