I certainly would not put it past any government to have a contingency along these lines. Though actually I suppose Stern should show that such a scenario is unnecessary. The cost of waging such a total and permanent resource war is going to be a lot more than the 1% of GDP he reckons we need to avoid the worst effects of climate change anywyay. Then again, it's not necessarily those bits of the western economies that are currently powerful who will benefit from Stern spending", and they are powerful enough to be able to seek protection in different government responses."
