If SS Vaterland [the world's largest ship at the time] struck an iceberg in May 1914 on its way to New York and on its maiden voyage and sank with heavy loss of life [more than 500-1000 dead], and assuming the assassination of Archduke Franz Ferdinand and the path to WW1 still break out [besides the Empress of Ireland's sinking] as in otl [real life], with WW1 to start on 28 July 1914 despite the disaster, what happens if an iceberg claimed the world's largest ship to the seabed for this 2nd time?
