Today is the fortieth (40) anniversary of the shootings at Kent State University in Ohio, May 4, 1970. Four students were killed and nine injured. Their protest was over the bombing of Cambodia. No one has ever been held accountable for those shootings.
The bombings by the United States set the stage for the Khmer Rouge and the 'killing fields' which, by 1979 produced the deaths of 3 million innocent Cambodian civilians. In 1979 communist Vietnam invaded Cambodia and toppled the Pol Pot Khmer Rouge Regime.
America, through the Nixon administration secretely bombed and invaded Cambodia at various times during the Vietnam War. Subsequently, the Carter administration backed the Pol Pot Khmer Rouge even though they thought Pol Pot was an abomination.
It appears only the Kent State Students had it right.
