How does Robert Baer use imagery in Sleeping with the Devil: How Washington Sold Our Soul for Saudi Crude?

Imagery:

"Bandar was not someone to be joked with, even by the president's CIA director."

"The United States had made a pact with the devil and was going to stick with it until the catastrophic end. As long as Sultan kept buying American weapons and Aramco kept banking our oil, no one in Washington cared what was happening in the kingdom."

"Washington made us lie down with the devil. It made the bed, pulled back the covers, and invited the devil in. We whispered in his ear and told him we loved him. When things went a little wrong, Washington held his hand and said it was all right. And all that time we had our eye on his bulging wallet, lit by the moonlight on the dresser."
