Citation needed for "reasonably viewed". For example, Stalin said this to Mao in 1949:
"In China a war for peace, as it were, is taking place. The question of peace greatly preoccupies the Soviet Union as well, though we have already had peace for the past four years. With regards to China, there is no immediate threat at the present time: Japan has yet to stand up on its feet and is thus not ready for war; America, though it screams war, is actually afraid of war more than anything; Europe is afraid of war; in essence, there is no one to fight with China, not unless Kim Il Sung decides to invade China?
Peace will depend on our efforts. If we continue to be friendly, peace can last not only 5-10 years, but 20-25 years and perhaps even longer."
