but maybe you can explain why they omitted canada? it's right up there in supplying oil to the usa:
The USA imports about 55% of its oil needs.
Sources of U.S. Oil Imports (millions of barrels per day, 2001):
Canada: 1.79 - Saudi Arabia: 1.66 - Venezuela: 1.54 - Mexico: 1.42 - Nigeria: .86 - Iraq: .78 - Norway: .33 - Angola: .32 - United Kingdom: .31 - Total: 11.62. (Source: Energy Information Administration).
Sources of U.S. Oil Imports (%, 2002): Saudi Arabia: 16.9% - Mexico: 15.1% -
Canada: 15.0% - Venezuela: 14.4% - Iraq: 11.4% - Nigeria: 5.9.%.
only about 30% of the USA's oil imports came from Arab countries in 2002. Since USA oil imports are about 55% of USA oil consumption, only about 15% of USA's oil consumption is provided by Arab countries.
