Simply put: Bush and Cheney and their band of neo-conservative war hawks, with their special relationship to the capacities of Israel in Iraq and across the Mideast, were given a chance.
The chance was to deliver on the US strategic goal of control of petroleum resources globally, to ensure the US role as first among equals over the next decade and beyond. Not only have they failed to "deliver" that goal of US strategic dominance, they have also threatened the very basis of continued US hegemony, or as the Rumsfeld Pentagon likes to term it, "Full Spectrum Dominance".

The Bush Doctrine was and is a neo-conservative doctrine of preventive and preemptive war. It has proved to be a strategic catastrophe for the US role as sole superpower. That is the background to comprehend all events today as they are unfolding in and around Washington.

The taboo of speaking publicly of the pro-Israel agenda of neo-conservatives has apparently been broken. That suggests that the old-guard foreign-policy establishment, types such as Zbigniew Brzezinski and Brent Scowcroft and their allies, are stepping up to retake foreign-policy leadership.

In the space of 12 months, Russia and China have managed to move the pieces on the geopolitical chess board of Eurasia away from what had been an overwhelming US strategic advantage, to the opposite, where the US is increasingly isolated. It's potentially the greatest strategic defeat for the US power projection of the post-World War II period. This is also the strategic background to the re-emergence of the so-called realist faction in US policy.
Realists? Hahahahaha! More like rats are abandoning the sinking ship. It’s the old “Family Circus” technique of “Not Me.” Who broke that lamp? “Not Me", the little ghost says.
