The notion that resistance points are openly stated at the end of negotiations is false as they are typically kept secret for strategic reasons. It's false that Americans and British gave up Mississippi claims for peace, and true that the Treaty of Paris ignored American Indians.
The statement that each party's resistance point is openly stated at the conclusion of negotiations is false. In political bargaining, parties may have undisclosed resistance points – the points beyond which they are no longer willing to negotiate. These resistance points are often kept confidential to maintain a strategic advantage.
An open declaration at the conclusion of negotiations is not typical as it could reveal weaknesses or undermine future bargaining positions. Moreover, when parties have opposite objectives that are non-negotiable, consensus becomes unattainable, often leading to status quo preservation.
Regarding historical claims to the Mississippi River, it is false that both the Americans and the British gave up claims for the sake of peace. In the Treaty of Paris, the British recognized American rights to the Mississippi. Lastly, it is true that for all practical purposes, the Treaty of Paris ignored the American Indians, as it did not effectively represent their interests in the peace negotiations between the British and the American colonists.
