VILNIUS, Lithuania (AP) — The United States and other major industrialized nations are pledging long-term security assistance for Ukraine as it continues to fight Russia’s invasion. At the annual NATO summit, G7 countries began laying the groundwork for member nations to negotiate individual security agreements with Ukraine. Ukrainian President Volodymyr Zelenskyy says the commitments will be a bridge toward eventual NATO membership for his country. He is desperate for Ukraine to become a NATO member so it can take advantage of the alliance’s security guarantees. But membership for Ukraine has remained elusive at the summit, held this year in Lithuania. Zelenskyy and Biden met separately as well.
