Is accepting mistake enough?

US secretary of State Hillary Clinton accepted that part of the war against terror they are fighting is created themselves. (See the full story here)

"Part of what we are fighting against right now, the United States created. We created the Mujaheedin force against the Soviet Union (in Afghanistan). We trained them, we equipped them, we funded them, including somebody named Osama bin Laden. And it didn't work out so well for us," 

I appreciate the courage and honesty, required from her part to openly accept the fault, that has caused countless death, violence, political unrest and disturbance throughout the world.  Every policy maker has to think of all the possible consequences, while deciding on very critical issues pertaining international issues, or else the result is in-front of us. Just to weaken the then Soviet Union, US has created a Frankenstein monster which ultimately caused the fall of its creator itself. 

(Incidentally I watched Stallone's Rambo3 last day which metaphorically and unintentionally tells this story. Its VHS release is dedicated to brave Taliban fighters! Stallone can follow up this story as Rambo5, were John Rambo fights against the innocent kid to whom he gifts a used bullet shell in the climax, who in course of time goes on to become Osama.)

But the most important question is, has they learned from this mistake? Are the policies that they are taking in international issues currently or the issues they endorse openly, adequately fool proof? Will they, or any other nation in the world cause the rise of another Osama, due to petty selfish decisions made just to boost an over inflated nation wide ego?
