Final answer:
The principle 'pacta sunt servanda' indicates that treaties must be kept, but in practice, the Treaty of Paris did not ensure protection for Loyalists or address the American Indians' stake in the war, showing a discrepancy between treaty ideals and outcomes.
Step-by-step explanation:
The term pacta sunt servanda is a principle in international law that means agreements must be kept. This includes treaties, which are legally binding agreements between states. In the context of your question, regarding the Treaty of Paris, it generally means the treaty should be performed by the parties to it in good faith. However, the historical record reflects that, although the Treaty of Paris was designed to end hostilities and start a peaceful era between the United States and Great Britain, the reality was more complex. Loyalists were not always protected nor well treated after the treaty, contravening the ideal of 'pacta sunt servanda'. Also, the treaty failed to address the interests of American Indians, who were stakeholders in the war's outcome, hence not honoring the full spirit of agreement as a comprehensive peace solution.
