A top US envoy to the European Union delivered a stark warning to allies about a proposed 'Made in Europe' defense initiative. Ambassador Gordon Sondland cautioned that this plan could severely disrupt existing defense supply chains and compromise Ukraine's ability to sustain its fight against Russia. The envoy's remarks underscore deep concerns about potential fragmentation in NATO's defense industrial base. While details of the 'Made in Europe' plan remain scarce, the envoy's warning suggests it could force allies to prioritize domestic production over established transatlantic partnerships, raising questions about cost, timelines, and interoperability. This development represents a significant geopolitical risk for defense contractors heavily reliant on cross-border cooperation.
