@SUD:
In typical US fashion your gov’t has withdrawn from ITER, preferring to go its own way. There are many reasons for this; however, at least one of them is because you have not been able to get your own way, and the US was not able to dominate the governing body. So, you have taken your marbles and gone home.
WRT, I know a bit of nuclear fusion, and what I will tell you was that it [US withdrawing from ITER] didn’t have that much to do with so-called “Yankees always want things their way” as SUD so diligently mentioned. The main problem was government spending. Initially, US was a major proponent in getting nuclear fusion power plant to work (expected to a prototype fusion reactor by 2025). However, that was when Congress initiated huge paycuts (literally hundreds of millions of dollars) from nuclear R&D, and called for that sector to be restructured into something much boarder and more science based (ie cutting back on long term technology for short term science). This caused the department to lose 800 scientist and several of our production facilities. This is not to say that the US government was against alternative energies, but also wanted to invest time to other, more conventional projects like hydroelectric, solar, and wind power (already billions of dollars had been invested in fusion research).
However, that doesn’t mean we have pulled out of ITER entirely, in fact we’ve sent several scientist aboard to Japan and Europe to help them out. Also our department is very willing to show our own findings with the ITER and help them out in any ways possible besides costly funding (as said before, Congress rolled back a lot of research spending). Hopefully we can continue to help them with the sciences involved in self-sustaining plasma research in order to power their own technologies.
Now there is a very strong possibility that US will rejoin ITER. This is due because of funding, something the remaining members of ITER are having problems of there own. But in a promising indication, the ITER agreed in 2000 to design a much smaller prototype capable as serving as model for a nuclear fusion plant at half the cost ($4 billion). Also promising is the fact that Congress has reinitiated some funding into Nuclear Fusion.
Seriously, imagine the laugh the rest of us will have if we are successful. Superpower one day, 3rd rate banana republic the next. Going to cost you big time to buy your way in later.
Actually, the strongest possibility lies that it will be the other way around (US first to develop a nuclear fusion power plant before the parties aforementioned). From what I can tell, US is still the dominant power in the field of modern nuclear fusion (esp. for Californians! :)) and is responsibly for much of science that governs it. By not joining ITER, we can now spend the increased funding in domestic research Department of Energy, Defense Programs, and Fusion Energy Sciences, which have made sustainable gains in this field – with the possibility of joining the ITER in the near future.

@EmuGod:
Actually, the biggest problem with Nuclear Fusion is that it requires the use of more energy to squish the Hydrogen atoms together than the energy you get out of fusing the atoms.
As I said before, the science is not so much as the problem but technology and cost. A very small fusion power plant can be build, but an actual one would require billions in spending and technology. We can get our energies from electromagnetic fields and Advanced Tokamak to exploit the use plasma pressure. I believe that the ITER is using a standard Tokamak (Donut design), whereas the US has already discovered much more efficient ways (NSTX) in which to manage plasma (another reason why we opted out from ITER).
I bet Alabama, kentucky and some of those southern states wouldn’t notice it much . . . .
Yeah, those Northern Yankees are always finding ways to put us down. Fight the power! :)
