Final answer:
Tecumseh was a staunch opponent of the United States, working to unite Indigenous tribes in resistance, implying that he saw the US as a destructive force to Indigenous peoples, not a nation to cooperate with.
Step-by-step explanation:
Based on historical accounts, we can conclude that Tecumseh did not believe in cooperating with the United States but rather saw them as a threat to Indigenous peoples. Tecumseh and his brother Tenskwatawa were against the American influence and the sale of Indigenous lands to the United States. Tecumseh worked to create a strong Indian alliance to resist American expansion, which ultimately became part of the conflict in the War of 1812. His resistance, along with that of his followers, indicated that he believed the United States would continue its efforts to destroy Indigenous communities unless they were met with a united and robust resistance.
