Answer: Nationalism
Explanation:
" Nationalism in the United States is a tricky issue which has come to the forefront in recent years. Nationalism, which is a political system that puts one’s nation above all others, should be separated from patriotism, particularly as nationalism is often driven more by racial and ethnic superiority than a love of country. While patriotism can be seen in 63 percent of Americans reporting being either extremely or very proud to be an American, it should also be noted that 55 percent of people felt that white nationalism posed a very or somewhat serious threat to the U.S. Nationalism can be seen in many aspects of America today, from politics to the economy to right-wing extremism."
