It may be expensive to extract deuterium from seawater; the issue is that we won't have to buy the deuterium from another country. Oceans we got.
There is no technical reason why the U.S. must be energy-independent, and certainly the economic reasons are all against it. The politics of not being energy-independent, however, have become intolerable. The key to making peace in the Middle East is to make oil worthless. (Fusion, or fission for that matter, is only half of that battle, I might add.)
Certainly we should be building fission plants today. The West needs desalination and we all need the electricity. I'm aware of no state other than my own in which any such nuclear plants are even on the drawing board, however...and we're just looking at building one in the next ten years.
If what you say is accurate, however, then we do need to pursue fusion research for that point in our future in which you show that our uranium runs out.
But do we have to perform such research with France and China?? That leaves a bad taste in my mouth...

Columbus' goal was to find a trade route to India and/or China that didn't have to go through the ME. The ME was rendered irrelevant as a result, although the trade route he was looking for turned out to be blocked by a land mass. Let the region be irrelevant again.
