Below

                              their length in months. Time periods
                              are rounded up or down for ease of
                              comparison. Current conflicts are
                              italicized and are colored red. The
                              longest wars are listed first in
                              descending order by lenth. The start
                              dates reflect when the United States
                              entered the wars.
