This time he's saying that Ariel Sharon's critical health is due to God punishing him for his policies.
Robertson's pronouncements are simultaneously disturbing and entertaining, but they do nothing to help the cause of Christ nor international or internal politics.
Robertson has previously called upon the US Government to assassinate Hugo Chavez, and called upon God to judge some local US county for rejecting intelligent design.
If you are sick and tired of Robertson and want action, I suggest you write a letter of complaint to ABC Family, the cable network that runs The 700 club which Robertson controls and stars in. Ask ABC family to pull the program from its schedule. Robertson will probably come back on some other channel, but pulling him from ABC Family will send a clear message.
