Rumsfeld is doing a great job, especially considering how much Pentagon internal (Army in particular) and Congressional (using military budget as district pork) resistance there is to his reforms. After huge reductions in military during Clinton years, he won two wars in record time, and now getting ready to do the same with Iran. He offered to resign 3 times, lest be a "political" liability only, as if another SecDef would be immune from liberal attacks - whether we stay in Iraq, or pull out of Iraq. It's their way of getting to higher targets - pull some "bricks" from under them. It was State (Bremmer et al) that "ran" Iraq for over two years after Iraqi Freedom, not the US military (unlike Germany and Japan for 7 years post-WWII), so we know where the responsibility lies for whatever mistakes were made there from summer 2003.
In any case, we already won "war in Iraq", and "war in Afghanistan", no matter that media and libs want to make it into a "loss" or "Vietnam". These are now just really bases for operations against Iran, which is a real next target. al-Sadr is nothing without Iran. So is Syria, which is why we didn't bother with them by now. Once Iran undergoes a regime change (internally or after bombing their nuke sites) their clients like Syria and al-Sadrists in Iraq and Hezbollah are done and Middle East is mostly pacified. This will also majorly pi$$ off Russia and China, because they're being left without clients and their sphere of influence in Middle East is reduced immeasurably, just like Chirac immediately became nobody from being a "protector" or "Godfather after fall of Saddam. Then it will also become much, much easier to deal with NoKo situation through China. Kim may finally get the attention he craves so much, though he may not like the kind of attention he gets. In other words, all roads now lead to Teheran, everything else (Iraq, Syria, Lebanon, Hamas, NoKo) follows - or, more accurately falls apart of its own weight. Till then, let's just not make too many mistakes in Iraq and elsewhere, lest it become a distraction to ultimate victory.
The Greek King Epirus, after what you might call a Phyrric victory, coined the phrase "Another victory like this and we're lost." We're not going after Iran during President Bush's time in office.

State ran the reconstruction (right into the ground), but security aspect was entirely handled by the U.S. military. The reconstruction failed, in large part, because we couldn't maintain security outside the wire. That made an already mismanged reconstruction effort impossible.
Other than that, your post is a lot of wishful thinking.
