Even the unstated but important motives driving opposition to the pipeline are hogwash. The environmentalists to which Mr. Obama is pandering have an understandable, if at times irrational, fear of oil spills and a religious faith in the dangers of global warming. The only problem is that blocking the pipeline will, if anything, increase the likelihood of oil spills because Canada will still bring the oil to market. But if it can't sell it to America it will sell it to China, which will bring it home via tankers, which spill more often -- and more calamitously -- than pipelines. Moreover, China will still burn the oil, meaning the effects -- real or alleged -- on global warming will be the same (or marginally worse, given the "footprint" of tankers). Also, the U.S. will still buy oil -- only we'll get more of it from the Middle East, again via tankers, deepening our dependence on their oil (another Obama bugaboo).
