Holocaust Museum said ISIS has carried out genocide against the Yazidis, but its investigation did not cover Christian persecution. Now there's concern the U.S. State Department might do the same, limiting any genocide pronouncement to Yazidis without mentioning Christians.

A similar move is underway in the British Parliament. Earlier this month, more than 30 religious leaders and scholars wrote Secretary of State John Kerry asking for a meeting to discuss what's happening to Christians and other minorities. Nina Shea organized the effort.

Historians debate to this day whether Fidel Castro was a communist from the time he took power or only became one after he was spurned by the United States. What is not disputed is that he was always an autocrat moving ruthlessly against anyone who dared oppose him.

Fidel Castro was loved and hated passionately.

Fidel Castro was not interested in personal enrichment. His supporters say he deployed his enormous authority on behalf of health, education and welfare programs that brought Cuba attention around the world.

As his country crumbled around him, Fidel Castro's stature diminished abroad and at home.

Donald Trump seems to prefer people he sees as being on his side.
