This week a very public spat erupted between President Donald Trump and Ukrainian president Vlodomoyr Zelensky after Washington took the unprecedented step of starting peace negotiation talks with Moscow - but without Kyiv.

After Zelensky accused Trump of disinformation, Trump retorted by branding Zelensky a dictator, something that has been roundly condemned by European leaders.

So why has Trump turned against Zelensky, what is behind his embrace of Russia and is his view shared by Americans?

Plus: How do you end a war? Do they always end in negotiations, as the cliche goes? And is there a fair way to do it - particularly if neither side has been militarily defeated?

Professor Sir Lawrence Freedman, the Emeritus Professor of War Studies at King's College London, looks to history to discuss all these questions and more.

As the first phase of the Israel-Hamas ceasefire-hostage deal enters its final weeks, the region is on tenterhooks to see what will happen next.

Will the rest of the hostages be released and aid continue to enter Gaza? Or will the deal be blown up and fighting restart? And as we mark 500 days since the October 7th massacre, we’ll be asking to what extent Israel has achieved its original war aims.

Plus, we go behind the scenes at the most dramatic Munich Security Conference yet, and look at why deputy US vice president JD Vance’s speech left European leaders speechless.

In a recent address to NATO in Brussels, U.S. Defence Secretary Pete Hegseth declared that the U.S. is no longer "primarily focused on Europe's security." He emphasised that the U.S. would not send troops to Ukraine and would 'no longer tolerate an imbalanced relationship which encourages dependency'. With the American commitment to global peace since 1945 now over, what does this shift mean for European security? Can Europe defend itself without American troops, funding, and intelligence support?

Plus: is the Trump administration signalling a move towards a multipolar world, where global power is divided into three distinct spheres of influence?
