Canada PM: Iran threat shows need for Keystone oil pipeline

OTTAWA - Iran's threat to block the main oil shipping route out of the Gulf points to why the United States should approve the Keystone XL pipeline from Canada to Texas, Canadian Prime Minister Stephen Harper said on Monday.
"I think it's pretty obvious what the right decision is ... not just from an economic and environmental standpoint, but from an energy security standpoint," Harper told CBC television.
"When you look at the Iranians threatening to block the Strait of Hormuz, I think that just illustrates how critical it is that supply for the United States be North American," he said.
Iran has threatened to block the Strait, at the mouth of the Gulf, should the West impose tougher sanctions on its oil industry as part of a standoff over Tehran's nuclear program.
