The UK Prime Minister, Keir Starmer, emphasized his efforts to unite NATO allies following a clash between Ukrainian President Volodymyr Zelensky and US President Donald Trump. Starmer traveled to the UK to address the divide caused by the conflict and, at a summit in London, urged European leaders to increase defense spending to support NATO. The clash led to the breakdown of a US-Ukraine deal, prompting concerns about reduced reliance on the US. Starmer highlighted Europe's potential role in peacekeeping if a deal with Russia is achieved.
