After the West Texas fertilizer explosion

And that would be a perfectly legitimate argument to make, if the
builders of the pipeline didn't already have an alternate pipeline,
through a different country, planned.

How do you make a pipeline from Canada to the USA pass through a different country than Canada and the USA?

As it is, the choice isn't
between 'no oil' and 'pipeline', but between 'pipeline to/through the
US' and 'pipeline into Asia'.

How do you make a pipeline from Canada to Asia????I do hope you meant that they declared the intention to SHIP the extracted oil to interested asian states.
