Americans are divided about how involved the United States should be in the problems of other countries. They also do not agree whether U.S. economic involvement in other nations such as trade is good or bad. These are some of the findings of a report released Thursday by the Pew Research Center. The poll was conducted last month and questioned 2,000 voters. According to the report, 57 percent of Americans want the U.S. to deal with its own problems. And, they say they want other countries to do the best to solve their own problems. Among Americans, 41 percent say the United States is doing too much in the world; 28 percent say the United States is doing about the right amount; and 27 percent say the U.S. is doing too little, Pew said. There is a difference in opinion among supporters of the two major U.S. political parties. Among Republicans, 62 percent say the U.S. should first deal with its own problems. Among Democrats, 47 percent have the same opinion, according to Pew.
