Today marks three years since Russia's full scale invasion of Ukraine began. As Europe prepares to boost its defence in preparation for a future possible war with Russia, we ask: what has the British army learned from the Ukraine war?

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.Contact us with feedback or ideas:battlelines@telegraph.co.uk @venetiarainey@RolandOliphant

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.Contact us with feedback or ideas:battlelines@telegraph.co.uk @venetiarainey@RolandOliphant

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?Roland Oliphant is joined by Ed Arnold, Senior Research Fellow for European Security at RUSI, and by Michael Ignatieff, the former leader of the Canadian Liberal Party and leader of the Opposition.Contact us with feedback or ideas:battlelines@telegraph.co.uk @venetiarainey@RolandOliphant

USAID is dead. From Ukraine to Vietnam, the knock-on effect from Donald Trump and Elon Musk's dramatic shuttering of one of the largest aid agencies in the world is being felt around the world. Why has it been shuttered and what does it mean for American soft power?Roland Oliphant speaks to Sera Koulabdara, CEO of Legacies of War, about the halt of de-mining work in southeast Asia and why it is essential for American influence in China's backyard. Plus he talks to The Telegraph’s senior foreign correspondent Memphis Barker about why Kyiv is especially worried and whether this might prompt a rethink of the international aid system.Contact us with feedback or ideas:battlelines@telegraph.co.uk @venetiarainey@RolandOliphant

Amid news of Iran developing new ballistic missiles and unveiling an underground missile city, we look at the truth behind this show of force. With its axis of resistance across the Middle East in tatters and ongoing internal issues over women's rights, the economy and the environment, we ask - can the Iranian regime survive 2025?Plus: We catch up with exiled Iranian director Mohammad Rasoulof about his new film The Seed of the Sacred Fig and ask what he thinks will happen to the Iranian regime.Contact us with feedback or ideas:battlelines@telegraph.co.uk @venetiarainey@RolandOliphant

As shock waves continue to reverberate through the US tech industry, The Telegraph’s AI and cybersecurity expert Gareth Corfield explains why a new AI Cold War is developing and what it means for Western security. Plus, we speak to a Doomsday Clock scientist about why AI means humanity is closer to disaster than ever before, and look at what the Trump administration's approach will be to the conflict in Congo and the African continent at large.Contact us with feedback or ideas:battlelines@telegraph.co.uk @venetiarainey@RolandOliphant
