NATO leaders tread carefully after Putin threatens war

US President Joe Biden and UK Prime Minister Sir Keir Starmer have met to discuss Ukraine as NATO considers allowing the country to strike deep inside Russian territory with Western weapons. While some NATO leaders say Ukraine has the legal and moral right to conduct these strikes, others warn there needs to be adequate consideration of the risk of escalating conflict with Russia.
