Worldview honors Memorial Day with the special “At War in the Pacific”, the story of young American Marines who stormed the islands and fought from inside foxholes during the bloody Pacific Campaign of World War II. Filmmakers Steven Spielberg and actor Tom Hanks offer their views on what the war in the Pacific meant - then and now. Worldview returns on Tuesday with a look at efforts to keep invasive species at bay here in the Great Lakes region and globally.
