When BC is starving to death they will allow a pipeline. 
When the USA places their duties of 50-70% on their clear cut lumber / forced to spend 100 million on sewage treatment because they can't unleash all their feces into the ocean.....yep, likely the hypocrites will need a little starvation before coming to their senses. Thats when we can get it to the asian markets. If this turns ugly for Canada it will be a matter of months before we are in deep trouble.
