The correct answer is Option A: because people of the world- including dissenters in Germany- has approved their cause.
Joesph Stalin justified the war of Soviet Union with Hitler's Germany because he believed that everyone was on his side. He believed the world had approved his cause to fight tyranny.
He also believed many Germans did not like Hitler and were also supportive of his cause.
We should not forget that the people of Soviet Union were already supporting Stalin.
