What you call “the first part” is actually the start of the last chapter of all, and which continues with: “We ask to be near to God, we fight you and destroy you and terrorize you. The Jihad in god's cause is a great duty in our religion. We have news for you, the news is: You will be greatly defeated in Afghanistan and Iraq and that America will fall, politically, militarily, and economically. Your end is very near and your fall will be just as the fall of the towers on the blessed 9/11 day. We will raise from the ruins, God willing. We will leave this imprisonment with our noses raised high in dignity, as the lion emerges from his den. We shall pass over the blades of the sword into the gates of heaven.” It’s worth reading in full to understand how they think and what their beliefs are.
