There are big shifts taking place on the global stage

and there are potential implications for the island of Ireland.

Not that the politics of this place, north or south,

can compete with the breathless turn of events in the Middle East and Ukraine,

in US-Russian relations and in the long-established transatlantic partnerships

between America and Europe,

but still the fallout from those twists and turns will inevitably have consequences in both Belfast and Dublin, and there could be an impact on the ongoing constitutional debate too.

We're bringing these strands together on this week's red lines, looking back to the reaction we had to last week's edition of The View. And also taking one of those talking points,

Professor Pete Sherlo highlighted to his audience in Coal Rayne,

essentially asking how protected people here would feel

if they were to become reliant on the Irish defence forces

rather than the UK military and how that possibility

might impact thinking in the run-up to a future border pole.

With me, to discuss all of that, Mark Hennessey from the Irish Times, Sam McBride from the Belfast Telegraph and Sunday Independent,

the veteran journalist Mary Kenny, who writes a column for the Irish Independent and the former

SDLP leader, Column Eastwood. So welcome to all of you and thanks very much indeed for

joining us today. Let's just start with the big picture. President Donald Trump is the new

sheriff in town again and he's wasting no time in shaking things up. What are the potential

consequences of the emerging new world order for the island of Ireland, Mark?

Well, they're very serious. Obviously, Ireland has, the Republic has a concentration of

FDI, a lot of it, US-owned. We have had a very successful tax record over the last number of years,

quite spectacularly so, in of years quite spectacularly so.
