Philippine President Rodrigo Duterte doesn’t want the U.S. military to establish a naval base in his country, saying that he fears the site would be a target in a future nuclear war between the United States and China.

“You put up a base at this time? This will ensure that a war breaks out because there will be atomic arsenals brought in,” Duterte told lawmakers Monday during a State of the State address. “This will ensure the extinction of the Filipino race.”
