The CNN Republican Presidential Candidates debate from Las Vegas this week was focused entirely on national security issues, but the word biofuels was actually uttered by one of the candidates who put forth the idea of using energy as a weapon.

“We ought to be challenging not only Russia, but the Iranians and the Saudis, on the point of energy,” said former Arkansas Governor Mike Huckabee during the first debate panel. “We ought to be drilling every bit of oil, getting all the coal out, we need to be going after our natural gas and biofuels, and become the energy exporter of the world.”

Huckabee argued that such an approach would “destabilize” the enemies of the United States. “We need to take an offensive approach by using our energy, the one weapon we have,” he said. “Let’s use it as an offensive weapon to change the dynamics of the entire globe and especially change the dynamics of the Middle East.”
