Speaking from the NATO summit in Ankara, Nick Fishwick assesses the alliance's most urgent challenges, from Europe's push to increase defense spending to the need for greater intelligence sharing and military interoperability. He explains why a peace agreement between Russia and Ukraine remains unlikely, what NATO is learning from Ukraine's battlefield innovation, and why Russia continues to represent the alliance's principal security threat. Fishwick also discusses the diminishing focus on Greenland as the war with Iran reshapes U.S. priorities.
