Forget the environmental argument. Forget the "jobs" argument. I believe the proposed Keystone pipeline is a national security issue! It will be over a thousand miles long and be run across large, sparsely populated areas. It is an extremely vulnerable terrorist target. And we Americans won't get a drop of gas from it. The sole purpose of the line is to deliver Canadian tar sands oil to Texas for processing and export. Why in the world should we take on the liability of this project and get nothing in return?
