President Biden’s high-profile diplomatic trip to the NATO summit in Europe has revealed some tensions in the U.S. relationship with Ukrainian President Volodymyr Zelensky. Zelensky believes that not including Ukraine in the alliance will allow Russia to continue its aggressive actions. Biden has halted NATO’s acceptance of Ukraine into the alliance, citing the mutual defense agreement and the fact that a war with a NATO ally is a war with all. National security spokesman John Kirby acknowledged the frustrations but stated that including Ukraine in NATO isn’t likely. While Biden and Zelensky demonstrated a strong bond during the summit, they disagreed on Ukraine’s readiness for NATO membership. Zelensky expressed dissatisfaction with the lack of a timeline for joining NATO and emphasized the importance of meeting security conditions. Biden believes that Ukraine should join the alliance after the war with Russia is over and when Ukraine’s security is guaranteed. The relationship between Biden and Zelensky has had its challenges, but they have maintained a strong personal bond. Despite the recent tensions, it is believed that their relationship will withstand these obstacles.
