That quote seems to come from the testimony of R. James Woolsley [1], who was referencing this commission report from 2008: http://www.empcommission.org/docs/A2473-EMP_Commission-7MB.pdf http://www.empcommission.org/docs/A2473-EMP_Commission-7MB.p... [pdf] Unfortunately discussion in this thread will be dead before anybody will finish comprehensively reading that report. With the recent failure of the federal government during what should be a significantly easier to manage emergency, I find the 90% to be more believable than I would have just a year ago.
