While the insurgents failed to do serious harm to the embassy and its staff (though there were numerous Afghan casualties) they did seem to gain a PR victory due to the amount of media attention the incident received.
ISAF went on a PR offensive of its own, though, including a great twitter fight between ISAF and the Taliban during the kinetic assault. These videos are another part of that offensive. Just like insurgents love to broadcast their battlefield exploits, NATO is now showing off it’s fighting prowess in a timely manner. Enjoy.
