I'd been optimistic that the release of the newer National Intelligence Estimate on Iran and the apparent ascendancy of a more rational point of view within the Bush administration might lead to a more cooperative attitude from Russia with regard to the continuing concerns about Iran's enrichment activities. That seems to not be the case, as Russia goes through with a nuclear fuel delivery that had been stalled for a bit. The Bush administration is taking a restrained line, presumably because they don't want the Russians to start considering bad behavior on the Iran front an important point of national pride and principle, but this is definitely a step in the wrong direction.
