"Biden's Diplomatic Tour: From London Talks to NATO Summit"

US President Joe Biden concluded his talks in London with British Prime Minister Rishi Sunak, where they discussed various global issues, including the war in Ukraine. Biden then visited King Charles III at Windsor Castle to address the challenge of climate change. He later traveled to Vilnius, Lithuania, for the NATO summit, where discussions are expected to focus on NATO's support for Ukraine and Sweden's bid to join the alliance. Biden expressed doubts about Ukraine's readiness for NATO membership but stated that the US would provide support to Ukraine similar to that given to Israel. He also expressed a desire for Sweden to join NATO "as soon as possible" in a phone call with Turkish President Tayyip Erdogan.
