As Donald Trump prepares to re-enter the White House, Mark Damazer reflects on America's leadership in the world.

Eavesdropping on a focus group recently, Mark tells us that the country's leadership was seen as 'a burden and a luxury - and a luxury they wanted to do without.'

'There was a time when large chunks of the world were grateful for American involvement...but gratitude is now more thinly expressed', he says. 'And Donald Trump well understands that.'

In this new world order, Mark argues, 'we have our work cut out to find a response.'
