Al-Qaida's Latest Threat

Given the vagueness and grandiosity of al-Qaida's latest threat, I suspect that they're waiting for a really big natural catastrophe that they can pretend they caused.

Addendum: There's an alternative explanation. They might be planning a lame attack on something symbolic of Menace. For example, they might set off a firecracker in front of a nuclear power plant or throw an apple sprayed with Alar in a city reservoir.

Addendum II: I've got it! They're trying to provoke bloggers into coming up with terrorist ideas. We can foil them by coming up with the most insane, unworkable ideas possible. These schemes are not only pro-mouse but based on real research.
