Answer:
The countries that have been traditional allies of the United States are Great Britain and Canada. In addition, other important allies are the members of NATO, France, Japan, Australia, South Korea and Israel.
Explanation:
US foreign policy states that its alliance with the United Kingdom as its most important bilateral relationship in the world, as evidenced by aligned political issues between the White House and 10 Downing Street, as well as joint military operations between the two countries. Although both the United States and the United Kingdom have close relations with many other nations around the world, the level of cooperation in military planning, the execution of military operations, nuclear weapons technology, and the sharing of information with one another has been described as "unprecedented" among the great powers throughout the twentieth and early twenty-first centuries.
The bilateral relationship between Canada and the United States is of fundamental importance to both countries. Between 75 and 85% of Canadian trade is with the United States, and Canada is the "largest trading partner and major oil supplier" in the United States. Although there are certain disputes between the two nations, relations between the two countries are close and both share the "longest demilitarized frontier in the world." The border was demilitarized after the War of 1812 and, in addition to minor incursions, remained peaceful. Military collaboration between the two countries began during World War II and continued throughout the Cold War on a bilateral basis and a multilateral relationship through NATO. High trade and migration between the United States and Canada since the 1850s has generated greater rapprochement, despite the continuing Canadian fear of being culturally oppressed by its neighbor, which is ten times greater in population and eleven times higher in terms of economy.
