How are Donald Trump’s ambitions in Venezuela and Greenland changing America’s place in the world? President Trump’s key adviser Stephen Miller has said that we are living in a world “that is governed by strength, that is governed by force, that is governed by power” - so where has that philosophy come from?

All this week, we are teaming up with our sister podcasts to explore how power and influence around the world is shifting. We exploring who is in a sphere of influence and who is being controlled by one.

Today, we speak to Anthony Zurcher, co-host of Americast and the BBC’s North America correspondent, about what US history tells us about this moment.
