That's fascinating.  I take it that you're expressing skepticism
at the idea that those ignorant savages could have influenced
the Constitution of the people who stole their continent.  You
could be right, but it sounds plausible to me.  Is there any
reason that you dismiss it out-of-hand?  Here's some more:

   Recent scholarship has shown that in the mid-1700s Indians were not
   only invited to participate in the deliberations of our "founding
   fathers," but that the Great Binding Law of the Iroquois Confederacy
   arguably became the single most important model for the 1754 Albany
   Plan of Union, and later the Articles of Confederation and the
   Constitution.  That this would be absent from our school texts,
   and from history, and from media is not surprising given the devotion
   Americans feel to our founding myth: Great men gathered to express
   a new vision that has withstood the test of time.  If it were
   revealed that Indians had a role in it, imagine the blow to the
   American psyche.
   ...
      By 1754, when most of these men and others gathered to creat the
   Albany Plan of Union, the first try at confederation, they invited
   forty-two members of the Iroquois Grand Council to serve as advisors
   on confederate structures.  Benjamin Franklin freely acknowledged
   his interest in the Iroquois achievement in a famous speech at
   Albany Congress: "It would be a strange thing...if six nations
   of ignorant savages[sic] should be capable of forming such a union
   and be able to execute it in such a manner that it has subsisted
   for ages and appears indissoluble, and yet that a like union should
   be impractical for ten or a dozen English colonies."
      According to Grinde, Franklin convened meetings of Iroquois chiefs
   and congressional delegates in order to "hammer out a plan that he
   acknowedged to be similar to the Iroquois Confederacy."

American Nation_ addresses this issue.
