Thomas Hobbes is known for his social contract theory. It explains that people within a government have obligations to fulfill for the country. The government, on the other hand, have to grant the rights of the people. Two are bound to each with a social contract, an agreement. However, if the government neglects its duties to the people, they have the right not to follow or replace those that are in the leadership.
They all have an effect on one another. With international trade comes trade embargoes if two or more nations don't get along. Global conflicts can also bring about a decrease in international trade for the offending nation as a sort of punishment. This is usually carried out by the UN but can also be done on a state by state basis.
