Answer:
The action taken by President Truman was as a result of the Soviet Union breaking the Yalta agreement. This made President Truman angry as he was against the spread of communism in Eastern Europe.
He wanted the Soviet leaders to know his real stance, tenacity and determination in opposing their plans. This was why Truman’s approach toward Molotov was justified. He was concerned on conveying this message to Stalin through Molotov about reminding Stalin to keep his promises of holding a free election in Poland.
