General Discussion

Although the contamination risk was a reason to oppose the Keystone pipeline what may have really killed it was that it was non economic to build it to transport the very dirty tar sands oil and refined it. Obama and Kerry stopping it when Obama was President delayed it enough that it was less viable in the first Trump administration.

I would imagine the cost of Venezuela's oil might be higher given Trump's and Rubio's statements could make the possibility of sabotage pretty high as they are saying they will steal it.
