The United States recently celebrated its Memorial Day, a national holiday when Americans commemorate and honor those who served their country, especially those who made the ultimate sacrifice.

The U.S. honors the ultimate sacrifice regardless of whether the war was just, later judged a mistake or involved actions that could be seen as war crimes. The focus is on the individual’s act of service.

Arlington National Cemetery has a section for those who lost their lives in the U.S. Civil War of 1861 to 1865, including those who rebelled against the U.S. at that time.
