Nuclear Security Summit To Discuss ISIS, N. Korea

The United States pledged Thursday to deepen cooperation with allies South Korea and Japan on deterring the North Korean nuclear threat, working to ramp up pressure following worrying provocations.

President Barack Obama didn’t disclose what further steps the countries might take as he met with Japanese Prime Minister Shinzo Abe and South Korean President Park Geun-hye on the sidelines of a nuclear security summit.

Regarding the summit, the U.S. said a strengthened nuclear security agreement among nations was finally set to take force, including new criminal penalties for smuggling nuclear material. The stricter rules for protecting materials and nuclear facilities worldwide were intended to reduce the likelihood of terrorists getting their hands on ingredients for a bomb.
