Ah. So if Sweden withdrew its military personnel from Afghanistan, no more jihad would be waged against it, right? That is certainly an assumption often taken for granted by Western analysts on both the Left and the Right: Islamic jihadists are provoked by our presence in their countries, and if we just left them alone, they'd leave us alone.
It is a comforting notion, at least to those who are so supine and addicted to their comfort that they'll sacrifice their freedom for it, but unfortunately for them, there was more in that audio file.
"Our acts will speak for themselves," said the message, "as long as you do not end your war against Islam and humiliation of the Prophet and your stupid support for the pig Vilks."
"The pig Vilks" is the Swedish cartoonist who drew the dog Muhammad: taking umbrage at the threats and murders of innocent people that followed the publication of cartoons of the Islamic prophet Muhammad in a Danish newspaper, Lars Vilks published his own cartoon of Muhammad as a dog with a human head. Islamic supremacists have put Vilks high on their hit list; last spring, he was attacked while he was giving a talk in Uppsala, and jihadists also tried to burn his house down.
