The '''Killing Fields''' is a collective name for several mass execution sites used by the [[Khmer Rouge]] regime during the communist sponsored '''Cambodian genocide''' between 1975-1979. An estimated 1.5 to 3 million innocent victims were murdered by the [[leftist]] regime after the Americans withdrew from Southeast Asia. Anyone suspected of cooperating with or harboring sympathies for the [[United States]] and [[capitalist]] system was exterminated.
Many [[Hmong]] refugees fled to the United States ftom [[Cambodia]] to escape the [[left-wing]] atrocities.
