Roger Waters has always let his opinion on war be known, especially in his music. In Pink Floyd, Waters brought up the effects of war with  The Wall and The Final Cut albums. He has now shifted his political views on the new US President, Donald Trump, the world is heading down a similar and frightening path.

In a new interview with Rolling Stone, Waters said “fighting is always about cash. War is hugely profitable. It creates so much money because it’s so easy to spend money very fast. There are huge fortunes to be made.”

And he’s worried that Trump sees war as a  lucrative reason for building up the U.S.’ armed forces.

“All the Donald cares about is business,” he said. “He cares about winning and losing at business. He just wants to be the strongest country in the world and to dictate what he believes to everybody else, and he is trying to do so and will continue to try to do so until the resistance grows to the point where hopefully he can be removed from office.”

Waters has also suggested staging The Wall at the U.S.-Mexico border in protest of Trump’s proposed wall. If that doesn’t end up happening, he hopes his upcoming tour will help anyway. “We have to organize our love in such a way that it becomes a potent and powerful enough tour to resist their narcissism and their greed and their callous disregard for the feelings of others and their absolute lack of the ability to empathize with anybody,” he told Rolling Stone. “It’s a lack of empathy that creates a true sociopath like Donald Trump.”
