1. The Romans did not consider the worst-case scenario when Hannibal crossed the Alps with his elephants and routed them; or when Hannibal encircled and annihilated the numerically superior Roman army at the Battle of Cannae.
Then, the Romans tracked him for the rest of his life and he died a broken man.
2. The Americans did not consider the worst-case scenario at Pearl Harbor or on September 11, and the results were disastrous for the American people.
Need I mention Hiroshima and Nagasaki?
3. American planners did not consider the worst-case scenario in its latest war
in Iraq, but instead operated on the "best-case scenario", such as considering the Iraq invasion a "cake walk" and that the Iraqi people would be parading in the streets, throwing flowers and welcoming American soldiers as "liberators", only to discover the opposite.
Errr! the democratic elections and Saddam and his gang rotting in jail cells waiting for the hangman.
I think, besides sweeping floors, this guy writes fortune cookie messages.
