The reason is that the fundamental economic problems associated with oil (national security, environmental, etc.) do not depend at all on whether the oil is produced domestically or abroad.
If the price of oil suddenly spikes, consumers in the United States are hurt just as much as consumers in Canada which is a net oil exporter. It doesn't matter whether the oil is foreign or domestic.
The problem is that we use oil, not whether the oil is foreign or domestic.
