In the past, NATO and Afghan officials have said most of the attacks are motivated not by support for the Taliban, but for "private reasons" including grievances against local Afghan commanders, ethnic feuds, and depression. Senior U.S. officials have insisted the attacks don't indicate a high level of Taliban infiltration into the army.
Today's video shows otherwise, suggesting that rogue Afghan soldiers who kill their American counterparts will find strong support among insurgents. The presence of so many young children in the video also suggests a new generation of green-on-blue attackers could be waiting in the wings.
"Are there others who will carry out attacks similar to what you have?" the rogue soldier is asked during the video.
"Yes" he replies. "There are some people who are looking for the opportunity to kill infidels. They will carry out their jihad and join us."
Likely, to a hero's welcome.
