Lessons Learned?

 Politico has an article summarizing views of the big shots from 2001 and leaders of the security establishment thereafter o

My own views:

• we should have more confidence in ourselves--in fighting terrorism we indulged in interrogation tactics and an approach, the military commission, to providing justice which revealed our lack of faith in established norms and institutions.
• we should have less confidence in ourselves--in our ability to figure out the unknown, whether Iraq had WMD, whether  we could do nation-building in Iraq and Afghanistan.
• we should always remember that we as humans don't do that well in dealing with the new and different, as we've seen more recently in dealing with covid-19.  We tend to react with emotion, with resorting to old patterns, with zeroing in on silos.  We must think anew and act anew.
