England could have prevented war in multiple ways between 1763-1781. The following are just a couple actions.
1) No taxes on the American colonists- One of the greatest factors that caused the American colonists to break free from England was the implementation of several different taxes after the French and Indian War. If the English crown never put these in place, many American colonists would have remained loyal to England.
2) Give colonists representation in English parliament- Another important cause of England's problems was that they were creating new taxes and laws for American colonists without hearing their opinions. The colonists had no representatives in the English parliament (the branch of government that makes laws).
