Tom Bradby and Robert Peston discuss President Trump's frenetic start to 2026, which has escalated fears of a military seizure of Nato territory Greenland.As Robert explains, Trump's obsession with the giant Danish island is not going to go away. Trump says it's in the interest of ‘national security’ - but is there something else driving him? Something which Greenland has - and which China has - that the United States doesn't?All of this comes just days after Donald Trump attacked Venezuela and captured its president Nicolás Maduro - and just before the US seized a Venezuela-linked Russian oil tanker for violating US sanctions.Tom and Rober discuss the potential consequences of two NATO allies being caught in a military standoff, and what Sir Keir Starmer can do to resolve tensions between the US and Europe - tensions that threaten to put the whole world in a much more dangerous place. Got a question for the team?
