Protecting the United States from terrorism means more to Americans than promoting democracy abroad, a Pew Research Center study found. Since the Sept. 11, 2001 terrorist attacks, Americans consider protecting U.S. shores from terrorism a top priority, according to a UPI report. The study, conducted every four years, found 83 percent of those questioned held that opinion in 2013, which is slightly down from its high of 86 percent in 2005.
