Against the USA:

Long-term damage:

Take out the Hoover and Grand Coulee dams, the Oil Terminal at Grand Island, and the 6 Biggest fuel pipelines including the Trans-Alaska. Guaranteed to trigger at least 2 quarters of recession along with other problems.


Horror:

1. Nerve toxin gas dispensed from several crop dusters at one or two of the big college stadiums during rivarly weekend. 80-120k per stadium.

2. Pirate an LNG transporter, sail it into a port like Frisco or Boston (most others aren't close enough to the ocean to pull it off, and then make the Halifax incident look like a small-town fireworks show.
