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.

Trump has always talked about how important in dealing with foreign leaders, how important it is to establish a good personal relationship very close to what Pope Francis says, so they may both really want to emphasize their development of a personal relationship.

Fidel Castro outlasted U.S. presidents determined to overthrow him, survived the collapse of the communist bloc that sustained him and outlived many of those who wanted to replace him. For those reasons, he will go down in history as among the world's most skillful politicians, even if his achievements largely die with him.

As Cuba's leader, Castro answered to no one and allowed no challenge to his authority.

Hispanics are the fastest-growing evangelical group in the country right now, an important constituency. But Trump's views, especially his views on immigration, did not exactly go over well with this faith constituency. Rev.

One of Donald Trump's criticisms of President Barack Obama and of Hillary Clinton was that they seemed reluctant to use the words radical Islam. It was not just semantics. Trump said it's important to name the enemy idea and then attack it. Consider the Cold War.

At one congressional hearing, Bishop Francis Kalabat complained that administration officials are overlooking what's happening to his fellow Chaldean Christians.
