It's taken out of context, if it does say that. I have never heard of it, so please show me it if you can.
A jihad, in a holy war sense, should be defensive in nature to protect Islam. Also, the Koran specificly protects civillian "people of the book" (Jews and Christians) during war. OBL ignores many of the teachings of the Koran, and his radical stance shows.
OBL claims the US and it's allies have killed millions of Arab civillians and to know their pain, we have to taste the bitter fruit as they have. Not too far fetched, but it's sad his "holy war" is based on revenge.
