Balls and Miliband are clearly trying to take advantage of the fact that, unlike David Miliband or Andy Burnham, they weren't MPs when the decision to go to war in Iraq was prosecuted – and so couldn't have voted either way. But I do wonder whether it will really do much good. After all, D. Miliband distanced himself from Iraq during the election campaign, saying that "If we knew then what we know now ... we wouldn't have gone in." And his involvement with the Blair government, and its decision, doesn't seem to have done him any harm in the leadership stakes so far.
Either way, at least the events of 2003 give them something to talk about other than the biggest political issue of 2010: the public finances.
