The square is a law that allows the government to draft young men into military service. Gulf of Tonkin Resolution Espionage Act

The correct answer is the Gulf of Tonkin Resolution.The Gulf of Tonkin Resolution was a joint resolution passed by the United States Congress in 1964 that authorized the president to take any measures necessary to repel any armed attack against the forces of the United States and to prevent further aggression.

It was enacted in 1917 during World War I and has been used to prosecute individuals for leaking classified information, including whistleblowers.Therefore, the correct answer is the Gulf of Tonkin Resolution, as it is the law that allowed the government to draft young men into military service during the Vietnam War.
