Xi Gives 3-Hour Speech

You have to look around for examples of speeches that last longer than an hour.  People just don’t have an attention span that supports listening that long.  The Castro family in Cuba was famous for long speeches, as were Hugo Chavez, and Saddam Hussein.  I can’t imagine a US President giving a speech more than an hour long.  The heads of state in Europe are equally thoughtful in giving speeches.  Too long, is too long.  It seems like only dictators give speeches that run for three hours.  Am I wrong here?
