There were many seperate conflicts in the so-called "Indian Wars," and although some (such as the forced movement of the Cherokee, or various of the infamous Indian massacres) were unjustifiable and definitely wrong morally in my eyes, there were many that were justified (namely fighting the Creek down in Georgia and Alabama, the Apaches in the Southwest, and the Blackfoot in the northern plains), as these tribal groups posed an immediate threat to our citizens from the word go. Actually, in the case of the Blackfeet and the Apache, they posed an immediate threat to all neihbouring Indian tribes as well as to ourselves. The Creek, likewise several northeastern tribes, had been allied with our enemies in the French and Indian War and the Revolution and the War of 1812, and received assistance from those parties when we fought the tribes themselves.
I would agree with your charges about several individual aspects of the Indian Wars, but overall I would have to disagree.
