Final answer:
Neoconservativism is not an isolationist policy; it actually promotes international engagement, particularly through military force, to champion U.S. interests and democracy worldwide, making the assertion false.
Step-by-step explanation:
The assertion that neoconservativism is an isolationist foreign policy approach is false. Neoconservatism is actually known for its advocacy of a strong national defense and a willingness to use military force to promote democracy and protect United States national interests abroad. This often results in more international engagement, rather than less. It emerged in the United States in the latter half of the 20th century and became influential in setting the tone for the nation's approach to foreign policy, particularly during the presidential administrations of Ronald Reagan and the Bush family.
