In 19th century, in America, there were cruel acts to slavery, especially The Fugitive Slavery Act. That was whoever see a run-away slave, they must return slaver to his or her owner. It was a law against humanity. Before this year, there was a tragic event that Congress pass Indian Removal Act , allowing Jackson to relocate eastern Indians west of Mississippi. So Indians was forced to be exiled, and sometimes they were killed without any guilty. Through these two historical events, as America established tremendous achievement, America politician’s viewpoint to aliens, foreigners also tremendous cruel. Today, America drives out country Which is against, or show different opinion to America. Americans believe, and insist “all men are created equal”. But their attitude of others isn’t fair. this is irony of America. I think America need to be more mutual, and have ability to find peaceful diplomacy.
