Rise of the Khmer Rouge

With the talk about President Obama refusing to allow troops to chase Taleban across the Pakistani border, I’m reminded of a story I read somewhere years ago that bombing across the Cambodian border in the Vietnam War destabilised the Cambodian government and allowed the Khmer Rouge to seize the country.

Any views on this? (I figured GD was a better spot for ths topic than GQ.)

Short answer: no. It was a popular idea back in the day but not well justified by evidence.
