Earlier today, the so-called Coalition of the Willing, largely made up of European leaders, met in Paris with envoys of US President Donald Trump, to try to make further progress on a sustainable peace deal for Ukraine.
With Ukraine's President Volodymyr Zelensky insisting a plan to end the war with Russia is "90% of the way there", no-one in that room wanted to jeopardise keeping the Americans onboard.
But there was an immense elephant in that grand and glittering Paris meeting and the underlying atmosphere was extremely tense.
Bear in mind the events of the last few days: the Trump administration's controversial intervention in Venezuela and the US president's insistence soon after, that "we need Greenland from the standpoint of national security".
Greenland is the world's largest island - it's six times the size of Germany. It lies in the Arctic but is an autonomous territory of Denmark's.
