U.S. President Joe Biden and British Prime Minister Keir Starmer are meeting to discuss loosening restrictions on Ukraine's use of Western-supplied long-range missiles to target deeper inside Russia. This comes amid renewed pleas from Ukrainian President Zelenskyy and concerns over escalating the conflict, as Russian President Vladimir Putin warned such actions would mean NATO is at war with Russia. Both Biden and Starmer have indicated that discussions will be strategic, with no immediate policy changes expected. Biden hinted at possible adjustments, noting that the U.S. is 'working that out now.' Meanwhile, Starmer emphasized that Russia started the conflict and has the power to end it. The talks are seen as potentially the last significant meeting on this issue before the upcoming U.S. presidential election.
