Does God Speak to Bush?

Commenting on the recent BBC claim that Bush advised Palestinian authorities that God told him to invade Iraq and Afghanistan, as well as push for a Palestinian state, Ira Chernus urges everyone not to "get too excited" about it. He adds:

There are so many more horrendous things Bush has said and done that deserve our harsh criticism. There are so many more ways he has used religious beliefs and religious language to justify immoral policies. Let's put our critical energy there, and not on one isolated statement that he'll go on denying he ever said.

Chernus thumbs through relevant material in his essay, but I disagree with his conclusion here. We should use any opportunity to pressure the White House to account for what type of influence Bush's religious fervor has on his Presidency, since I think it manifests itself in the confidence (which many read as "arrogance") with which Bush goes through on so many disastrous policy decisions.
