Operation Rolling Thunder was a sustained bombing campaign against North Vietnam. This was a campaign run by the troops of the United States and the Republic of Vietnam forces (South Vietnam) and took place from 2nd of March 1965 until 2nd of November 1968. There were several reasons for the operation including stopping the flow of North Vietnamese commodities and men into the South, bombing North Vietnam's transportation system and to boost South Vietnam's morale.
The Delano grape strike was a labour strike by the Agricultural Workers Organizing Committee and the United Farm Workers against grape growers in California. The strike began on September 8, 1965, and lasted more than five years. Due largely to a consumer boycott of non-union grapes, the strike ended with a significant victory for the United Farm Workers as well as its first contract with the growers.
The strike began when the Agricultural Workers Organizing Committee, mostly Filipino farm workers in Delano, California, led by Philip Vera Cruz, Larry Itliong, Benjamin Gines and Pete Velasco, walked off the farms of area table-grape growers, demanding wages equal to the federal minimum wage.[1][2][3] One week after the strike began, the predominantly Mexican-American National Farmworkers Association, led by Cesar Chavez, Dolores Huerta and Richard Chavez,[4] joined the strike, and eventually, the two groups merged, forming the United Farm Workers of America in August 1966.[3] The strike rapidly spread to over 2,000 workers.
