During President Clinton's watch, Muslim extremists declared war against the United States twice. The first act of war occurred in New York on Feb. 26, 1993, when the World Trade Center was bombed. Six Americans were killed and 1,000 were injured. The second act of war occurred on Oct. 12, 2000, when the USS Cole was bombed and 17 Americans lost their lives. Clinton ignored both acts of war, which led to a third act of war on Sept. 11, 2001. Our next president must understand that there are no diplomatic solutions because the war against Muslim extremists will be won or lost on the battlefield.
