All of it or just some of it? This part?
In the colonies the war was called the French and Indian War. Both the French and the British colonists were helped by their Indian allies. An ally is a friend in a war. The British army and British colonists were helped by the Iroquois Indians.
And two Mohicans! …. But that was the last of them!
Yup. That should be a part of the history that is taught. The biggest problem with teaching any 'history' of American Indians is that prior to the European invasion, there was little to no actual written history on the continent. Makes it hard to go into any deeper pre-columbian history, as what is retained was generally oral histories, little of which was recorded even by colonists, and much of that was somewhat romanticized.
Now, if they'd like to go into what is actually known about pre-columbian times, that would be fine, but I would object to romanticized 'noble savage' nonsense. The native tribes were every bit as violent, warlike, and territorial as every other human society on the planet. The fact that they never made any significant technological progress in their entire history (lacking even such basics as the wheel, and writing), was a major contributing factor to the ability of a more technologically advanced society to fully and unconditionally conquer them.
There did appear to be some tech of sorts in central and south america, but ultimately, they were still largely outclassed by their European foes.
