Who Was Neil Armstrong - 尼尔·阿姆斯特朗 THE U.S.S.R.—ALLY, THEN ENEMY

BY 1943, THE U.S.S.R.—ALSO KNOWN AS RUSSIA OR THE SOVIET¹ UNION—WAS FIGHTING ON THE SAME SIDE AS GREAT BRITAIN AND THE UNITED STATES IN WORLD WAR II.
WHEN THE WAR ENDED IN 1945 WITH GERMANY’S DEFEAT, THE FRIENDSHIP BETWEEN THE UNITED STATES AND THE U.S.S.R. ENDED, TOO. BOTH COUNTRIES WERE VERY POWERFUL. THE UNITED STATES SAW THAT THE U.S.S.R. HOPED TO GAIN CONTROL OF OTHER COUNTRIES IN DIFFERENT PARTS OF THE WORLD. THAT WOULD MAKE THE U.S.S.R. TOO POWERFUL.
WORLD WAR II WAS OVER, BUT THE “COLD WAR” HAD BEGUN AND LASTED UNTIL THE COLLAPSE² OF THE U.S.S.R. IN 1991.
