The United States will break its recent promise to approximately 200 countries to join in the fight against climate change if Sen. Ted Cruz (R-TX) is elected president.

That’s according to Cruz himself, who on Tuesday said he would withdraw the U.S. from the historic climate agreement reached in Paris earlier this month. That non-binding agreement saw nearly 200 leading nations unanimously embrace a plan that would leave most of the world’s fossil fuels unburned, thereby limiting global warming “to well below 2°C (3.6°F) above preindustrial levels.”

According to the Washington Post, Cruz said the international agreement was disingenuous — not really to fight climate change, but to gain “more and more government power.”

“Barack Obama seems to think the SUV parked in your driveway is a bigger threat to national security than radical Islamic terrorists who want to kill us. That’s just nutty,” Cruz said. “These are ideologues, they don’t focus on the facts, they won’t address the facts, and what they’re interested (in) instead is more and more government power.”
