President Joe Biden is set to attend the NATO summit in Vilnius, Lithuania next week. This summit comes at a critical moment for the military alliance, with mounting security threats from Russia and China. President Biden will deliver a significant address on the final day of the summit, outlining his vision of a strong America with confident allies and partners. The summit agenda includes discussions on Ukraine’s future membership, security guarantees, and assistance, as well as the issue of meeting the 2 percent defense spending target. Ukraine’s membership is unlikely to happen until the war in Ukraine ends, as it would essentially be a declaration of war on Russia. The United States, Germany, and southern NATO partners are cautious about Ukraine’s membership, while the Baltic states and Eastern European nations are more assertive. The summit will also address China’s rise and the strategic implications for NATO. There are also discussions on Russia’s domestic politics and the vulnerability it presents. Additionally, the summit will debate Sweden’s membership, as it is currently blocked by Turkey and Hungary. President Biden’s trip to Europe will also include stops in London and Helsinki, where he will commemorate Finland’s accession to the military alliance. Finally, next year’s NATO summit in Washington will mark the 75th anniversary of the alliance’s founding.
