Timothy Ash, Chatham House, Russia and Eurasia Programme Associate Fellow says "NATO is dead" but there are "silver linings" to the Oval Office row between Trump and Zelenskiy. The comments come after NATO Secretary General Mark Rutte told Ukrainian President Volodymyr Zelenskiy to repair his relationship with US counterpart Donald Trump after a public spat at the White House on Friday. The US and Ukraine failed to sign a critical minerals agreement after a meeting between Trump and Zelenskiy devolved into a fiery exchange, fracturing relations between the two countries. Qualifying the incident as "very unfortunate," Mark Rutte said in an interview with the BBC that he's spoken to Zelenskiy twice since and told him that "we really have to respect what President Trump has done so far for Ukraine." Ash Spoke to Caroline Hepker on Bloomberg Radio about the rapidly shifting geopolitical landscape.
