Iceland
Both Iceland and the U.S. are NATO allies, and the U.S. has maintained an interest in Iceland since the mid-1800s. The countries have had a relationship of mutual cooperation and support in the past few decades. However, according to a Global Leadership Report in 2012, only 17% of Icelanders approved of U.S. leadership.
Morocco
Morocco was the first sovereign nation to recognize the U.S. in 1777, and relations between the two countries were formalized in a 1786 treaty which is still enforced to this day, meaning that it is the oldest unbroken bilateral treaty in U.S. history. Morocco is one of the few African countries to extend visa-free travel for U.S. citizens.
