As we mark one year of Donald Trump back as president of the United States, we answer your questions with Matt Chorley on 5 Live. We start with Greenland, and ask whether the president can be talked down from his threats to impose further tariffs on countries who oppose his takeover plan. What’s been the response of Republicans, and who has the biggest influence on Trump when it comes to foreign policy?

Also, the US president reportedly sent a letter to Norway’s prime minister Jonas Gahr Støre, saying Trump no longer feels ‘an obligation to think purely of Peace’ after they awarded the Nobel Peace Prize to Venzuela’s María Corina Machado. More text from his reported letter here: “Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace, although it will always be predominant, but can now think about what is good and proper for the United States of America.”

The president has now said he will “100%” follow through on his threats to impose further tariffs on NATO countries if a deal over Greenland is not reached. Plus, after Trump told Iranians “help is on its way” following mass protests and killings, what happened behind the scenes for him not take military action?

And Robert F. Kennedy Jr has promised to ‘Make America Healthy Again’. When asked about Donald Trump’s diet, the health secretary said ‘I don’t know how he’s alive’, citing a diet of fast food, sugar and fizzy drinks. The team look at whether RFK Jnr is making ay progress on changing US eating habits, and what is happening with vaccinations for children.
