this is actually a psychological necessity on the part of a right wing that screws up everything it touches and is incapable of admitting its failure:

Conservatism's cherished fantasy of American omnipotence has died once again, this time in the sands of Iraq, and the grieving process has begun. But conservatives mourn differently from you and me. They begin with denial, anger and bargaining, just like everyone else. And that's where they stay--forever paralyzed by a petulant refusal to acknowledge their fantasy's passing, a simple inability to process reality.
