Keystone XL would hurt Russian allies

Diane Francis:

...
Clearly, the two must gear up for battle by deploying oil and natural-gas weaponry. The most immediate retaliatory blow would be the approval of Keystone XL from Canada. This oil pipeline would add 830,000 barrels a day into the US oil market, more than enough to replace the 755,000 barrels a day of oil imports from Russia’s western hemispheric ally Venezuela. 

A Keystone bomb would deliver several payloads: punishment toward anti-American Venezuela; proceeds toward Canada which buys more goods and services from the US than the European Union does; punishment toward Russia by casting into the markets more Venezuelan oil; replacement of Venezuelan oil with Canadian oil that is $30 a barrel cheaper (roughly 30 percent less) and even an improved environmental outcome.

The Venezuelan crude is actually more than twice as dirt as Canadian oil sands.  But the geopolitical aspects of the move should make it a no brainer, except that many on the global warming movement can't see beyond their own carbon phobias.  Venezuela is using the money to prop up its low functioning command economy and also using it to support enemies like the Cuban regime.
