Any and all of those sites would have been on a target list. The ones in Canada would have been on mine had I wanted to target US energy supplies.
Oil and gas pipelines, public knowledge, electrical transmission lines, power plants (coal and nuclear), damns, oil export facilities, narrow shipping lanes like the straight of Hormus.
By god if a group of terrorists did not think about these types of sites as targets they are pretty darn worthless as terrorists.
Give me a bunch of bombs and detanators along with 10 intelligent people and I could knock out about 15% of US energy supplies just from Canada. I didnt need wiki leaks to inform me of the potential targets in Canada
