In Washington, the capital of the United States, the 40-hour demonstration march against the U.S. imperialist invasion of Vietnam that began on the evening of the 13th continued on the 14th. The endless parade, braving storms and hail, passed through the gates of the White House and all the way to the U.S. Capitol. The demonstration was attended by approximately 46,000 people from various states. Most of the demonstrators were young people and many teenagers. They unanimously demanded that the Nixon administration immediately stop the war of aggression against Vietnam and withdraw all American invading troops from southern Vietnam.

On November 15, more than 300,000 people held a massive demonstration in Washington. Demonstrators came from all over the country. They started from near the U.S. Capitol, crossed Pennsylvania Avenue, past the White House, and marched to Washington Monument Square in the city center. The demonstrators chanted slogans such as "American invaders get out of Vietnam immediately" and "Recruit Nixon into the army." In San Francisco, demonstrations against the war of aggression, with more than 200,000 people participating mainly from cities in the western United States, also broke out on the 15th. Despite police threats, the demonstrators held a 12-kilometer-long march, and then held a protest rally to condemn the Nixon administration's aggressive policy and demand an immediate end to the war of aggression and aggression against Vietnam. From the 13th to the 15th, more than 1 million people across the United States participated in this demonstration against the war of aggression against Vietnam.
