99 | Trump Abroad

From the G7 to the Singapore summit, it's Trump's world: we just live in it.  This week we try to get some perspective on these spectacular events.  Is Trump's behaviour really unprecedented for an American president?  What is the point of the G7?  Where is his relationship with Kim heading?  Plus we compare with summits past: Nixon in China, Reagan & Gorbachev, or something new?  With Helen Thompson and Andrew Preston, who gives a Canadian view.  Next week: Grenfell.
