I never said risk wasn't inherent. I'm saying they calculated the risk incorrectly, and more importantly, it was calculated in a manner that was negligent or foolish even at the time it was done. Risk is inherent but it's still a stupid decision to 1)incorrectly evaluate the risk when the information to properly do so was available 2) pursue a course of action that may not be within your risk tolerance. I know you might just think I'm being contrarian but this issue matters for any similar future endeavors. This is not just a case of an ambitious program gone wrong, this is a case of poor planing, poor execution, and over exuberance. To say no one knew any better at the time this was done is simply not true. Plenty of people knew better, including the leaders themselves, and yet they chose to ignore obvious issues.
I think it's funatmentally incorrect to just look at this and say bad luck, or the risk didn't man out. There were so many failures at each step of the way this problem was one of European creation that could have been avoided, not some inherent risk that they rational chose to gamble on.
