A US writer and radio host says that the country's killing of civilians in Afghanistan serves the purpose of public intimidation.
"Things go back, I believe, to World War II, to intimidate the opposition. We did it ruthlessly in Vietnam, and the most well-known Operation Phoenix, with the estimated number of civilians that we killed, numbered maybe 80,000. The number could have been doubled," he added.
He said the United States military presences in Iraq and Afghanistan is tantamount to war crime.
