Which has practiced isolationism?

The United States

Explanation:

"American Isolationism While it has been practiced to some degree in U.S. foreign policy since before the War for Independence, isolationism in the United States has never been about a total avoidance of the rest of the world. Only a handful of American isolationists advocated the complete removal of the nation from the world stage." Based on that I'm pretty sure it's the United States.
