The latest Kristol-Kagan editorial argues that we have too few troops in Iraq, and that Rumsfeld should learn from his mistakes–or Bush should find a SecDef who will. Strong stuff, and I’m sympathetic to the view that we have had too few troops in Iraq. But didn’t Kristol and Kagan come out for Rumsfeld’s resignation from the administration back in 2001, when the China spy plane incident supposedly showed the administration’s lack of seriousness about national security? (They wanted Wolfowitz out too.) How many times can you go back to this well?
