The West is at a “crossroads in history,” Britain’s Prime Minister Keir Starmer told European leaders at a pivotal summit in London on Sunday, as the continent sought to wrestle control of negotiations over the Russia-Ukraine war away from the US and present a united front amid a meltdown in relations between Kyiv and Washington.

The urgency of the summit in London's ornate Lancaster House was heightened after US President Donald Trump chastised Zelensky in the Oval Office, appalling the West and delighting Moscow in the process. Zelensky and an ensemble of European leaders were in attendance, at a moment of intense anxiety in the conflict.
