"The best way to learn from mistakes is to recognize them, point them out, learn from them. and illiminate the them".......................I respectfully disagree. IMVHO, it is best to educate those individuals you would place into authority with countless years of very much and well documented history of trajedies long past. If one needs to examine every new disaster after the fact as you say. Should I expect the human race to continue after armageddon ?
Even if everyone were prepared as I indicate there would still be some mistakes made. The secret is to avoid the truly large ones if at all possible and to learn from them. The very method we document history and hope that leaders bring that documentation with them is through the method I described above. I expect that method will be ongoing until Armegeddon, after which time, our Savior will be on the earth. We will survive Armegeddon precisely because of His appearance IMHO.
