What country was the largest supplier of oil to the us when bill clinton was president?

United States imports oil from Canada. It imports about 70% of Canada's output. (That's a LOT).

However, 20 years ago, Saudi Arabia was the largest oil supplier to the United States. 

 Shay's rebellion was important to highlight the problems with the Articles of Confederation because it showed the people and government how terrible the Articles couldn't handle a crisis. 

 Many of the poorer people had to take large loans to keep their farms functioning while they were off fighting in the revolution. When the war ended, they had no money to pay the creditors back, who began pressing for the money. 

I hope this helps.
