Answer:
Isolationism is described as <u>D.internally focused foreign policy</u>
Explanation:
Isolationism is a foreign policy that believes in the government having an 'internal focus' where the government should try to improve to solve national problems before taking care of issues that are far from home.
Isolationism can be both political and economic. A isolationist political policy would mean that a country decides not to take part in world events and instead use their funds and energy internally.
An example of this can be countries like Switzerland, which do not take part in international wars and missions and only recently joined the UN.
An economic isolationist policy is when a country decides to not trade freely around the world. This might be to safeguard local natural resources or against foreign competition. There have been many examples of such countries, one of the best known being Japan in the early 15th century.
