Part of Saudi Arabia's discomfort with an American action to topple Saddam is the fact we are intent on replacing him with a representative government.

A genuine, functioning democracy in the Gulf is a threat to all autocratic rulers there. The Saudi Royal family is hanging on by a thread as it is, with both radical Islamists (like bin Laden) threatening it from one side, and those who chafe under the strict religious rule from the other.
