Keystone Pipeline / Strategic Oil Reserve

Our current oil reserve is in underground salt caverns drilled by the government. 727 million barrels approx. which could be consumed in about 32 days at our current consumption. In other words, it could be wiped out in one months time.
I'd like to see these reserves increased to 4 to 6 months supply.
Why not allow the pipeline with some stipulations that it would be responsible for maintaining the increased supply? This would give the pipeline some skin in the game of being a benefit to America.
Currently there is an environmental risk factor holding up the Keystone line with little benefits if oil is to be exported. (some jobs).
If we had a reserve that large it could also be used as a threat to market speculators that drive up the cost of oil.
Increase long term national security and price stability with a larger reserve.
