BLOWING UP THE BRIDGE:

President Obama's rejection of the Keystone XL pipeline from Canada to the Gulf of Mexico is an act of national insanity. It isn't often that a president makes a decision that has no redeeming virtues and -- beyond the symbolism -- won't even advance the goals of the groups that demanded it. All it tells us is that Obama is so obsessed with his re-election that, through some sort of political calculus, he believes that placating his environmental supporters will improve his chances.
Aside from the political and public relations victory, environmentalists won't get much. Stopping the pipeline won't halt the development of tar sands, to which the Canadian government is committed; therefore, there will be little effect on global warming emissions. Indeed, Obama's decision might add to them. If Canada builds a pipeline from Alberta to the Pacific for export to Asia, moving all that oil across the ocean by tanker will create extra emissions. There will also be the risk of added spills.

Now consider how Obama's decision hurts the United States. For starters, it insults and antagonizes a strong ally; getting future Canadian cooperation on other issues will be harder.
