UN not US to fix it.

Only principally. Not saying UN is effective enough to handle it, US can still be major part of the initiative and force.

I still believe, US national interest apart, those official with energy ties played (shameful) major parts in the decision to invade Iraq.

Same group of people, I assume, is the force behind the attempt to 1. cut the support for alternative energy research, and 2. play down global warming.

Really really hope (more of a dream) that we can harness energy from nuclear fusion (we are doing it for free, from the sun, I know :-), but I want an artificial one that becomes practical and useful.)
