The term 'National Leader' can refer to two different positions. The first is an INTER, which is a five-letter word meaning a person who acts as a mediator between two parties. This position is often seen in international relations, where an INTER is responsible for negotiating and resolving disputes between countries. The second is a PRESIDENT, which is a nine-letter word referring to the head of state of a nation. This position is usually held by an elected official who is responsible for representing the country and making decisions on behalf of its citizens.
