Please tell me-who are these people?

The question mark in the top row should not be Ho Chi Minh. Hu is an old man with a half-bald back and a goatee, not the figure in the picture. Hu died in September 1969, when he was 79 years old, and the American in the picture was Nixon, which means it was 69 years later. After the death of Ho Chi Minh, President of the Democratic Republic of Viet Nam, Sun Desheng was elected President. This Sun Desheng is the figure who represents North Vietnam in the picture, the third in the second row.

The three people in the bottom row are symbolic figures, along with American prisoners and symbols of American soldiers and special forces.

It is clearly written in the upper right of this picture that the United States has fallen into the quagmire of the Vietnam War. At that time, a lot of American economic power was wasted in Vietnam, and the death of a large number of American soldiers brought great dissatisfaction to the American people. It was already very difficult for Nixon to take office at this time. In January 1969, when Nixon took office, tens of thousands of people in Washington took to the streets holding placards such as "Nixon is the number one war criminal" and "Nixon is the tool of billionaires".

This picture shows that Nixon is seeking multi-party talks to solve the Vietnam problem. On January 27, 1973, after long-term negotiations, the United States signed the Paris Agreement on Vietnam with the Democratic Republic of Vietnam, declaring the failure of American military operations in Vietnam.
