The United States has vital economic and national security interests in deterring aggression and maintaining peace and security in Europe. But almost six months ago on February 24, a clearly undeterred Vladimir Putin launched the largest invasion on the European continent since WWII.

As the Ukrainian people continue the fight to defend their country, the war grinds on with no end in sight.

Meanwhile, Putin's disregard for the sovereignty of Russia's neighbors prompted Finland and Sweden to seek admission into NATO — even as NATO member Turkey fluctuates between cooperation and competition with Russia.

How are Russian and Ukrainian forces currently performing on the battlefield? What role has Turkey played in the conflict, and will this impact the future of U.S.-Turkey relations? Are recent changes to NATO's military posture sufficient? How should we view the likely addition of Finland and Sweden to the NATO alliance?

Bradley Bowman — senior director of FDD's Center on Military and Political Power (CMPP), filling in for host Cliff May — poses these and related questions to two experts.

LTG (Ret.) Ben Hodges previously served as the Commanding General of the U.S. Army in Europe and is now the Pershing Chair in Strategic Studies at the Center for European Policy Analysis.

Amb. Eric S. Edelman previously served as U.S. Ambassador to both Turkey and Finland and at the Pentagon as Undersecretary of Defense for Policy. He's now a senior advisor at FDD where he also serves on the Board of Advisors for FDD's CMPP.
