"They" meaning the Bush administration? Policy makers don't have to be competent. Only the people carrying out and enforcing the policy must be.

None of this is necessarily indicative of some sort of shadowy conspiracy planned and carried out by God knows whom, but I wouldn't rule it out based on speculations of competency.
