US and Europe commemorate D-Day, but is the peaceful post-war order under threat?

We take a look at the reaction to events in Portsmouth, where world leaders including Emmanuel Macron, Donald Trump and Angela Merkel gathered to commemorate the 75th anniversary of D-Day.

We then move to Ireland, where Donald Trump ended the day ruffling feathers - by drawing an awkward parallel with the US-Mexico border.
