"However, as Claudia Cattaneo pointed out in yesterday's Post, U. S. politicians are playing a dangerous and hypocritical game by criticizing oil sands as they are fretting about security of supply. Canada could certainly find other markets for such oil, although it would involve reversing pipelines, or building new ones. This would, ironically, reduce U.S. security and increase greenhouse gas emissions further. Republican candidate John McCain sounds a good deal more sensible on such issues, but even Mr. Obama will have to bow to reality if he reaches the White House."
