I want to revisit one of the darker chapters in our nation’s glorious story, the 9/11 terror attack that killed 3,000 or so innocent victims.

Netflix has produced a three-part documentary that chronicles the effort to hunt down Osama bin Laden, mastermind behind the 9/11 attack. It’s more than four hours of really gripping TV. It takes the viewer through all the pre-9/11 attempts to hit the United States. There are interviews with key officials from the Clinton, Bush and Obama administrations.

We remember what happened that day. It was a gorgeous September morning in New York. A jetliner crashed into one of the Twin Towers. Then a second plane tore into the other Tower. A third plane smashed into the Pentagon. A fourth jet crashed into a Pennsylvania field after passengers fought with hijackers for control of the doomed craft.

The documentary sought to assess responsibilty for the catastrophic intelligence failures that produced the tragedy. I didn’t hear one time the name of an individual at the center of the intelligence network, nor did I hear a single reference made to anything she did or didn’t do: Condoleezza Rice, national security adviser for President Bush.

It has been a major puzzle to me how in the world she has escaped any recrimination for the failure to detect or act on any clue that might have materialized prior to the events of that horrifying day. I recall at the time as the nation endured the shock of what happened that no one seemed to mention Rice’s name publicly. My goodness, she was at center of our nation’s intelligence-gathering network.

President Bush selected Rice to be his national security adviser because she is known to be a deep thinker, a critical analyst, one who studies her craft thoroughly … and for my money, someone who should be held accountable for whatever failings occurred on her watch that led to the mass murders and destruction of the World Trade Center.

The series concludes with a detailed look at the planning that went into the eventual killing of bin Laden by the SEALs. I was struck by this nugget as well. President Obama was told that his national security team had less evidence of bin Laden’s presence in that Pakisani compound than what was used to persuade Americans that Saddam Hussein had weapons of mass destruction. He didn’t have the WMD and we went to war in March 2003. All Obama had was purely circumstantial evidence that bin Laden was in the compound.

I am still waiting to learn, though, whether Condoleezza Rice ever will be asked to answer this question: Did you do all you could have done to prevent 9/11?
