I'm not trying to justify the delay in the pipeline because I'm not; it's ridiculous. But the oil flowing through the Keystone was never meant for the U.S. market. It was already planned for export.
Only after the feedstock has been refined....they are considering a relaxation of the definition of refined...in any event this oil replaces diminished supply fro Mexico, Venezuela and reduces dependency on mid eastern crude and is going to the gulf refineries because they are designed to accommodate heavy crude.
