"The United States has engaged in difficult diplomacy before, over things far more consequential, even, such as thermonuclear war."

"The United States is confronted by a cluster of national security threats that arise from our economic and cultural reliance on fossil fuels."

"To adequately prepare our military forces for future threats, we need to understand how climate change might be a source of war and, certainly, instability."

"We face a current dependence on oil, a large percentage of which is controlled by hostile or unstable regimes concentrated in the volatile Middle East."
