Usually when the Bush administration appeals a lower court ruling to the Supreme Court, I start feeling a little queasy. Not this time. As Miles Pomper points out in this WPR feature, there are some really good reasons to worry about relaxing restrictions on Russian uranium exports to the American nuclear industry. So much is made of the threat of fissile material falling into the wrong hands, and the program to downblend Russia’s weapons grade uranium is one of the few lasting successes of the immediate post-Cold War period. Finding a way to make the program attractive enough to renew it once it expires seems to me like it should be a priority as well. But for now shoring it up for the rest of its duration is a good place to start.
