Answer:
Vietnam War
Step-by-step explanation:
The My Lai massacre is one the blackest pages in American history. On 16 March 1968, between 347 and 504 unarmed vietnamese civilians were killed, women were gang-raped and children were mutilated. Of 26 soldiers charged with criminal offences, only one Lieutenant was condemned to a life sentence but served only 3,5 years under house arrest.
It is no surprise that these atrocities were fuel on the anti-war fire in the United States.
