Did they bother to check what percentage of US oil is imported from the middle east? According to the Dept of Energy, about 13% in 2000. If you cut out the countries that don't support terrorism, we're down to 5-10% of our oil?
They do address that in their FAQ
http://www.detroitproject.com/readmore/faq.htm :
"7) The United States only imports 12 percent of its oil from the Middle East.
That's a big 12 percent. The US imports 2.5 million barrels of oil a day from the Middle East. And Saudi Arabia is our second largest foreign supplier of oil. And at least partly to protect the oil, the US spends $60 billion a year to maintain our military presence in the Middle East."
Apart from linking SUVs to promoting terrorism I agree with much of the stuff on their site, SUVs are silly things.
