Archbishop John Wester agrees with Trump on nuclear weapons

A US archbishop and leading Catholic voice on nuclear disarmament has said he shares the US president's concerns over nuclear proliferation. His comments come as the third Meeting of States Parties to the Treaty on the Prohibition of Nuclear Weapons takes place at the United Nations headquarters in New York this week.

The nuclear states – countries with nuclear weapons – are headed by the United States and Russia, who each have more than 5,000 nuclear warheads. China is a distant third with just north of 400 nuclear warheads.
