And the rest of the world could call it whatever they like.  We'll continue calling it soccer, because it makes sense considering we already have a popular sport we refer to as football.

Only that this other sport does involve usage of arms, not feet.

That argument doesn't make sense. Soccer involves the use of your chest, knees, head, arms and hands. American football involves the arms, hands and feet. The only difference is the percentage of use.
