Step-by-step explanation:

Daniel Ortega in Nicaragua aligned with socialist movements, as did H.o Chi Minh in Vietnam, influencing the Vietnam War. In Korea, Kim Il-sung's leadership led to the division between North and South. China saw the reign of Mao Zedong's communist rule, followed by Deng Xiaoping's economic reforms.
