There should have been NO outrage of the execution of the north vietnamese SPY! Only the leftist radical communist in this country with the aid of KERRY, FONDA, CLARK, CLINTON et al brainwashed the majority of Americans that it is "evil" to kill anyone who is trying to murder you ... unless you are a Christian conservative, then you have no right to live according to the lawyer scumbags.
About that Vietnam-era photo of the execution of the Vietcong spy, this was shown over and over and over again ad nauseam of decades as an example of American-supported excess in Vietnam. But remember, there was only one media at the time, and no voice spoke up in opposition.
The left is good at crying crocodile tears.
