What may have strengthened Iroquois leaders' resolve not to ally with Britain?

Iroquois leaders may have been strengthened in their resolve not to ally with Britain due to a desire to maintain their autonomy and control over their lands, as British expansion threatened their territory. Additionally, the Iroquois Confederacy's longstanding trade relationships and alliances with other European powers, such as the French, could have influenced their decision to resist British influence. The historical context of British encroachments on their rights and sovereignty likely reinforced their determination to stand independently.
