A more thorough explanation:

Definition: A war zone is a designated area on land or at sea where belligerent countries do not respect the rights of neutral countries according to international law.

Example: During World War II, the Atlantic Ocean was considered a war zone. German submarines would attack any ships that were not part of their own navy, including neutral ships carrying supplies to other countries.

Explanation: The example illustrates how a war zone is an area where the rights of neutral countries are not respected. In this case, neutral ships carrying supplies were attacked by German submarines, which violated international law. The designation of the Atlantic Ocean as a war zone meant that neutral countries had to take extra precautions when sending ships through that area.
