When it came to thundering against the "Yankee imperialists!" Hugo Chavez sure talked a good one. But despite his bluster and monkeyshines he wasn't crazy enough to lift a finger against his top customer, or even wish him (genuine) harm. It's impolitic to reveal, but the U.S. is --by far--the biggest customer for Venezuelan oil. Hugo Chavez was our fourth largest oil supplier, behind only Canada, Mexico and Saudi Arabia.
