Sitrep Thursday 24th January

What’s behind last weekend’s car bomb in Londonderry?  We speak to Dr Marisa McGlinchey whose forthcoming book "Unfinished Business: The politics of Dissident Irish Republicanism" is out soon.   President Trump and North Korea are planning another summit  - but is North Korea still developing nuclear warheads?  Sitrep looks at the meeting from both the US and North Korean perspective with Robert E Kelly, Professor of Political Science at Pusan University in South Korea and Michael Stathis, Professor of Political Science and International Relations at the University of Southern Utah.   Michael Stathis also comments on the US shutdown and how it’s affecting defence and security.   And Glynn Prysor from the Commonwealth War Graves Commission talks to us about memorials and why they get vandalised.
