I just figured out Keystone!

The reason we need to import Canadian shale oil, skip 13 closer refineries, take it to Houston, refine it, pump it aboard an oil tanker, and ship it to Cuba is because they have no oil, and if we supply it, we can use those billions to pay for our rent to maintain our Guantamino military base, airstrips, and large military presence. And kick Mother Russia in the teeth again.

So, Keystone is an anti-Russian plot.
