The fundamental objective guiding a nation's foreign policy is

Step 1: Analyze the question The question asks for the fundamental objective (the main guiding purpose) behind a country's foreign policy. Foreign policy is the set of strategies a nation uses in dealing with other countries.

Step 2: Explain the concept Every country, whether Nigeria, the USA, or Ghana, designs its foreign policy to protect and promote its own national interest. This includes:

• Protecting its sovereignty and territorial integrity
• Promoting economic growth and trade
• Ensuring security and defence
• Enhancing its international image and influence
• Protecting its citizens at home and abroad

For example, Nigeria's foreign policy has "Africa as the centrepiece," but even that is pursued because a stable, united Africa serves Nigeria's own national interest.

Step 3: Evaluate the options

• A. National interest: Correct. It is the core driver of all foreign policy decisions.
• B. Colonial interest: Wrong. This reflects the priorities of colonial powers, not an independent nation's goals.
• C. Foreign interest: Wrong. A nation does not primarily serve other countries' interests.
• D. African interest: Wrong. It may be one of Nigeria's priorities, but it is not the universal fundamental objective for every nation.

Step 4: Answer The correct answer is A. national interest.

Exam tip: In Government questions on foreign policy, remember the phrase "Foreign policy = National interest." If you see "national interest" among the options, it is almost always the right choice for questions about the main aim, goal, or determinant of foreign policy.
