a bit arrogant as other people point it out but also makes a wrong comparison! WW1 lasted six years but the time wasted was much more, multiply it by the number

a bit arrogant as other people point it out but also makes a wrong comparison! WW1 lasted six years but the time wasted was much more, multiply it by the number of people involved (the soldiers alone were 68 millions) and the time spent on reconstruction and you got a much higher value, in the order of hundred of millions years.
