Notice how Kristol doesn't seem to be going after Colin Powell or Paul Bremer who respectively kept us from using as an immediate Interim Government, the Iraqi National Congress...which Rumsfeld had all ready to go as a replacement?
Instead, by letting the Iraqi's set up their own constitution first, it took an additional year of unnecessary wrangling. And for sure we should not have lingered with the process once we had Saddam. We should have just installed the moderates with a constitution, and walked away with some treaty and basing rights. And some oil would not have hurt either.
But no, they want to lay the whole rap on Rumsfeld. We could quintuple our forces in Iraq, and probably still not drastically lower ultimate casualties. We might finish sooner, but as long as Powell was messing around with this dithering time-wasting process, that was unlikely.
