There has certainly been progress; I guess the question is more a political one: is there much of a future for a multiparty ruling coalition in Iraq? Or will the Shiites simply dominate the Sunnis? I think that is what WFB is reacting to.
The way the Iraqi constitution is structured, there almost has to be a coalition government. The Sh'ia are in the majority--that's a fact. They will be the most influential group, but they are not a monolith. It is too simplistic to think of just three factions--Kurds, Sunnis, and Sh'ia. It has more to do with tribes and other centers of power. It will take a while to work things out.
It has been less than three years since we went into Iraq. Remarkable progress has been made. It will take patience and perserverance to succeed. Democracy and stability in Japan, Germany, and South Korea didn't happen overnight. It took many years to reach a level of stability and order. The MSM and the Dems have created unreasonable expectations hoping that Bush will fail.
