Biden's Diplomatic Mission: Navigating Divisions and Galvanizing NATO on Ukraine

President Biden is heading to the NATO summit in Lithuania, where divisions over Ukraine's desire to join the alliance and Sweden's stalled bid for membership are expected to dominate discussions. Biden's ability to keep NATO unified in responding to Russia's aggression is crucial for his reelection pitch, but with Turkey blocking Sweden's accession and concerns over escalating tensions with Russia, unity may be difficult to achieve. Biden's position on Ukraine's membership remains unclear, but he is expected to offer security guarantees to Ukraine without committing to immediate membership. The summit will also address defense spending and the need for a united front against Russia.
