After Iraq invaded Kuwait in August 1990, Bush imposed economic sanctions on Iraq and assembled a multi-national coalition opposed to the invasion. The administration feared that a failure to respond to the invasion would embolden Hussein to attack Saudi Arabia or Israel, and wanted to discourage other countries from similar aggression. Many in the international community agreed; Margaret Thatcher stated that "if Iraq wins, no small state is safe." Bush also wanted to ensure continued access to oil, as Iraq and Kuwait collectively accounted for 20 percent of the world's oil production, and Saudi Arabia produced another 26 percent of the world's oil supply.
