Answer:
Yes.
Step-by-step explanation:
Yes, In my opinion Great Britain had the right to expect Americans to help pay the cost of the French and Indian War because Great Britain are the owner of the southern colonies in the land of America and the Americans that lives there are the citizens of Great Britain so as a citizen of the state, they have the responsibility to help its country in the time of wars and pay taxes to fulfill the cost of the French and Indian War.
