If Trump were to declare that national security requires that taxpayers prop up coal-fired plants, coal mines and older nuclear stations, it would be for political reasons, not because of any threat to national security.
President Obama didn't wage a "war on coal," as Trump has often claimed. Trump hasn't made the US an energy exporter. He also doesn't seem to have a good grasp on what "clean coal" is.
Environmental Protection Agency (EPA) chief Scott Pruitt says former President Obama declared "war" on coal and other industries with his administration's environmental regulations and by signing of the Paris Climate Accord.
