What should be placed on a diagram with Country divided at 38th parallel, Communist invade from the north, and fighting stop in 1953?

World war 2
The Korean war
The Vietnam war
Cuban missile crisis

The Korean war.

The diagram represents the Korean War. Here is how you can determine the answer:

1. Read the information provided:
- Country divided at 38th parallel
- Communist invade from the north
- Fighting stops in 1953

2. Understand the context:
The 38th parallel refers to the line of latitude that divided Korea into two parts after World War II. The northern part was occupied by the Soviet Union and became a communist regime, while the southern part was occupied by the United States and became a democratic regime. Eventually, North Korea, the communist side, invaded South Korea in 1950, starting the Korean War. The fighting lasted until an armistice was signed in 1953, which stopped the active combat.

3. Compare the information with the answer options:
- World War 2: This option does not match the information provided. World War II occurred before the Korean War.
- The Korean War: This option matches all the information provided, including the division at the 38th parallel, the communist invasion from the north, and the fighting stopping in 1953.
- The Vietnam War: This option does not match the information given. The Vietnam War had no direct connection to the 38th parallel or Communist invasion from the north.
- Cuban missile crisis: This option does not match the information given. The Cuban missile crisis was a conflict between the United States and the Soviet Union in 1962 and did not involve the division at the 38th parallel.

Therefore, the correct answer is "The Korean War."

The diagram should contain the following:

- The map of the country divided at the 38th parallel, with a clear line separating the two sides.
- Arrows or symbols indicating the direction of the Communist invasion from the north.
- A label indicating the Korean War, which is the conflict that occurred with the Communist invasion.
- A label indicating that the fighting stopped in 1953.

The diagram should not include World War 2, the Vietnam War, or the Cuban Missile Crisis as they are separate conflicts and not directly related to the situation described.
