If I understood your question correctly, then the answer is "it depends". Sometimes, individuals have a large impact on starting a war (think World War I where one individual caused the war to start), other times groups of people have also important roles in starting a war (think World War II).
Right to command the military, make treaties, and the president also has the right to grant reprieves and pardons.
It depends on the time period. In the 1600s when they just settled in Jamestown, they most likely didn’t know that they were there (at least how many were there) but later, of course they started driving them off so they could build more of America. I’m actually studying this in school right now so I hope I am correct. Don’t be sure this is right though...
