Al-Quaeda video: prelude to an attack?

In the latest lunatic raving video to come from al-Quaeda, Ayman al-Zawahiri and American Adam Gadahn issued a dawah, an invitation to Islam. As I've mentioned in previous posts, it was the practice of Muslim armies to first invite their opposition to convert to Islam, then slaughter those who refused.

"It is time for the unbelievers to discard these incoherent and illogical beliefs," he said. "Isn't it the time for the Christians, Jews, Buddhists and atheists to cast off the cloak of the spiritual darkness which enshrouds them and emerge into the light of Islam?"

The dawah could be a signal to al-Quaeda cells and affiliates to launch pre-planned attacks against American targets.
