Richard Lugar actually said...

"We must take whatever actions are necessary to reduce our dependence on foreign oil."

"about half of our substantial military budget goes, one way or another, to protecting our oil trade"

"Isn't the urgency of this such that a more dramatic push is really in the national interest?"

"For the better part of 50 or 60 years, our foreign policy had been deeply entwined with oil, in one form or another."
