Just as World War I didn’t prove to be “the war to end all wars,” the 20th century didn’t turn out to be when the nearly unimaginable brutality and indescribable evil represented by German dictator Adolf Hitler’s Nazi regime was definitively laid to rest.The evil is back. Big-time.This time it’s in the form of the militant Islamic State of Iraq and Syria (ISIS), which is battling to take over Syria and Iraq and has already blurred the two countries’ boundaries. It’s leaving trails of bodies -- and horrors -- in its path.
