Given the substance that was used to murder Alexander Litvinenko, it looks almost certain that the Russian government was at the very least complicit in the crime, although the Daily Telegraph might be blaming Conrad Black, and from an ethical point of view the expulsion of 4 Russian diplomats is certainly justified. That doesn't mean that it is a good idea though, I've been saying for several months that the Russian government seems intent on creating a siege mentality* to justify further erosions of liberty at home. In theory Vladimir Putin has to stand down at the end of next year, a looming foreign policy crisis could be enough to provide a pretext to extend Putin's time in office. Obviously Litvinenko cannot simply been forgotten but it would seem prudent to pursue the suspects without giving Putin an excuse to whine about being victimised,
* For instance the Estonian statue furore, or the missile defence row or the disruption of gas exports etc.
