Moosa claims that the historic 2018 North Korea–United States Singapore Summit, where Donald Trump had a meeting with Kim Jong-un, was brokered by him. A Zambian news outlet reported that Moosa enlisted the help of Paul Manafort Jr. and sent a hand-written letter to Donald Trump advising him to back-off from his standoff with North Korea. He claims that he wrote similar letters to Speaker of the House Paul Ryan, Prime Minister of Shinzo Abe of Japan, and Crown Prince Mohammad bin Salman of Saudi Arabia. In the news report, Moosa stated that he helped bring peace between the United States and North Korea because prior to Adnan Khashoggi's death, Moosa spoke to him on the phone and he told Moosa about North Korea's nuclear missiles and extreme military power. Moosa states that a confrontation with North Korea would result in a Third World War, which had to be prevented at any cost.
