Answer:
Unity under one government
Explanation:
Having a high opinion can mean that you see the value of something or somebody. Having sufficient power and their own specific interests are restricted to the 1st person singular or plural in a selfish manner. The intelligence of other countries is not something that crosses your mind when you think of your country. The unity under one government is what the history of the United States of America (the independence) has taught American people to appreciate, nourish and value.
