What area of the world was Japan trying to control?

well, without the bill of rights, our basic rights as U.S citizens could be taken away and if the government becomes entirely corrupted, people could be put in jail for false accusation, their race, religion or even sexuality, and many other unfair circumstances.

we also wouldn't have freedom of speech.

anti-federalists held that a bill of rights was necessary to safeguard individual liberty as well.

hope i helped luv (: have a nice rest of your day.
