I did not know that (about oil)

I can’t remember where I read it, but a columnist I respect said that we can’t possibly go to war with Iran because Iran’s strategic location on the Persian Gulf means that it could choke off our oil supply.  Ed Lasky, however, thinks that is a 1970s view of oil needs and supplies, and provides us with a more current view about available oil supplies and the need for oil.  If Mr. Lasky is correct, Iran’s threat to cut off oil to the world isn’t the nightmare scenario it would have been 30 years ago.
