The military’s energy consumption has steadily grown as its arsenal has become more mechanized and as US forces have had to travel farther distances.
“In World War II, the United States consumed about a gallon of fuel per soldier per day, according to the report. In the 1990–91 Persian Gulf War, about 4 gallons of fuel per soldier was consumed per day. In 2006, the US operations in Iraq and Afghanistan burned about 16 gallons of fuel per soldier on average per day , almost twice as much as the year before.”

“With wars in Iraq and Afghanistan and troops spread around the world, the Department of Defense is the nation’s biggest oil consumer, burning 395,000 barrels per day — about as much as Greece.”
”“Here is our current defense posture,” Rep. Steve Israel said. “We are borrowing money from China to fund our defense budgets to buy oil from the Persian Gulf to fund our military to protect us from China and the Persian Gulf. It is an insidious vulnerability.”
Everything that has happened since 2000, has been written about in 2008, in The Project for A New American Century, publication, Rebuilding America’s Defenses.
Check out that paper. It is a very interesting read.
“ESTABLISH FOUR CORE MISSIONS
for U.S. military forces:
• defend the American homeland;
• fight and decisively win multiple, simultaneous major theater wars;
• perform the “constabulary” duties associated with shaping the security environment in
critical regions;
• transform U.S. forces to exploit the “revolution in military affairs;”
Everything that has happened, has been laid out in this paper written in 2000. Members of PNAC include Elliott Abrams, Gary Bauer, William J. Bennett, Jeb Bush. Dick Cheney, Steve Forbes, Zalmay Khalilzad, I. Lewis Libby, Dan Quayle, Donald Rumsfeld, Paul Wolfowitz.
Back to more of your question, it is hard to compare war times and “peace” times, because with troops stationed in 130 countries, it is hard to ever have true peace. Our military is going use as much oil as possible if it will be profit for oil corporations.
The most damaging part of the war, is that all of the new money being printed to support it, cause debt, inflation, and unfair spending practices. The new money being created to support the war, go directly to corporations, who in turn get to spend the newly created money on necessities(oil, houses, etc.) which drive up demand, which drives up prices, which lowers the value of the dollar. It is a ruthless cycle, and as long as we give the “Federal” Reserve the power to print money so the government can use all the resources it wants, to do what it wants.
Watch this movie to see how money is created to see how our government does whatever it wants, while we have to pay it back in the many years to come.
