In the name of fairness: not long ago I posted an article criticizing the Obama administration for participating in the preparations for the Durban 2 hatefest. Yesterday the State Department announced that having tested the waters they'd decided not to plunge in, essentially continuing the policy formulated by the Bush administration of boycotting the conference. A number of European countries are mulling the same - after all, it's the Obama Americans who are boycotting the conference, not the Bush ones.
All in all, the process seems reasonable. The new folks inherited a rather unusual position - America doesn't often boycott things - so they went to check what it was all about. Having learned first hand, they understood the inherited position was correct, and they affirmed it. Can't do better than that, it seems to me.
