Is the u.s imperilistic

I bealive that the us is very imperialistic. We take land even though we are not suposed to. We have expanded to much we need to shut down some of our bases around the world but that wont happen for a long time because we are to militay based of a country. We have the biggest military in the world and we have the most money but we most of the problems.. poverty,homeless,murder and other things. We need to pull back form all other states untill we can fix our problems THEN and only then do we need to go back and help other with theier problems and tats why I think we are imperialistic.
