Which of the following illustrates Congress's role in national security?

A. We need to send field operatives to country A to assess the situation.

B. Mr. President, our dollar is not strong enough to finance that mission.

C. We should negotiate a treaty with country Z to fix this situation.

D. Mr. President, we are sending 10,000 troops to country B next week.

The answer is B) Mr. President, our dollar is not strong enough to finance that mission.

The Congress's role on national security implies directly on the negotiations with another country, especially when they involve difficult situations, that is the option C. (We should negotiate with treaty with country Z to fix this situation).

International relations are built through agreements between countries. This means that before any direct intervention in another country, one must try first - through diplomatic means - to agree to solve problems.

Remembering that priority number 1 is to protect the citizen and society.

For the other answers:

A. In practice this is done quite a bit today, which partly solves the question of national security, but can not be simplified that way.

B. This is more of a strategic economic issue than of national security.

D. This is also done today, which does not solve the question of national security because it involves a very high cost for the country and implies international inquiries about the influence exerted on the sovereignty of smaller countries.
