Explanation:

The Tet offensive was a military operation planned by the government of North Vietnam and executed by the North Vietnamese Army and the Vietcong in 1968, against the US-led allies, especially the Army of the Republic of Vietnam (ERVN) , Army of South Vietnam), during the Vietnam War.

The planning of the offensive was meticulous and the execution well done; but the military results were disastrous; not so the political consequences, especially in the United States. The large number of US soldiers killed during the offensive, about 14,000, was not digested by the American people. The rejection of the war in the United States increased and that meant a turn of the war towards the defeat of the coalition. Some authors consider that it was a tactical defeat, since in addition to dying tens of thousands of North Vietnamese fighters, they lost the totality of the conquered. However, it is considered to be a strategic victory due to the subsequent change that it caused in the US military strategy.

social contract theory basically says that all individuals are born equal, and provided a god given right to consent to be governed. american government is based of this

thomas hobbes and john locke said that we are selfish, individualistic, and constantly at war with each other, therefore we need to be controlled. 

government is defined as the legitimate use of force to control human behavior within territorial boundaries, here comes in hobbes and locke.

hobbes takes the part about controlling human behavior. while locke takes the part of legitimate use of force, since force is not legitimate unless there is consent of the people. 

there are basically 3 goals of the government: 1) maintain order by protecting life and property. 2) providing public goods, those which are typically not provided by the public sector, such as roads and education. 3) promote equality be it political, opportunist or outcome equality.
