He commented that the Caribbean earthquake was God's vengeance due to the Haitian's pact with the devil. Apparently, back in 1804 (when America was only on their third president) the Haitian locals sat on ole' Beelzebub's lap and said "Please, help us win a bloody revolution against our colonial masters across the Atlantic."
History is an evasive mistress. Giuliani forgot about the Septemebr 11th terrorist attacks ("We had no domestic attacks under Bush...") and Robertson forgot about America's own revolution.
In Robertson's defense, he may have sincerely thought that Americans negotiated their freedom over afternoon tea in Boston.
Pat Robertson reads the Old Testament and sees God's wrath, but stopped before he got to the New Testament where God shows his love for the world. If Pat Robertson didn't get to 33 A.D. he sure doesn't have time to read about 1776, 1804, or 2005.
Actually, I feel bad for Pat Robertson. He thinks that God is so vengeful that if you screw up he'll kill you. And he won't just strike you down with lightning, he'll send a force that will kill you, your family, your neighbors, a fair number of citizens in your town, 3 random tourists, a stray dog, and that plant hanging from the rafters on your porch.
I'll conclude with a page from Pat Robertson's book (don't read the whole Bible, just quote the parts that reinforce your point). Read Hosea 14:4 and Matthew 6:14.
