Take the following as truth: Critics say expansion could be another Yalta (the 1945 meeting at which Roosevelt, Churchill, and Stalin agreed on spheres of influence in postwar Europe)--imposing a line between East and West, and leaving nonmembers subject to Russian bullying.
Then the following statement: "Expansion proponents did not consider the results of  the leadership meeting at Yalta in 1945." is true, false, or inconclusive?
Answer: Inconclusive
