america hasn't saved NOBODY.
Biggest America's "achievements" are killing millions of people: dropping two nukes on Japan out of desperation killing over 1 million, dropping agent orange on Vietnamese killing another 1 million people, destroying N. Korea in 1950s..etc.
Russia saved Europe in 1812 from Napoleon's wars, in WWI and WWII.
Cold War ????? You don't know what you're talking about
