Who was dumb enough to say that there ever was? Russias like the poorer, less successful version of the US. If they had the capabilities and influence the US has, they would have done the same mistakes murica has, probably even more.
Finland attacked the USSR first in 1939?
The USSR's morbid fantasy of fighting a war with the US led to their economic collapse, which resulted in billions of dollars of weaponry flooding into the 3rd world and destabilizing it like it never was before. Name one war after 1920 where the US was not acting as a reactionary force, that is the difference.
The most controversial conflicts were Iraq and Vietnam, as controversial as they were they were still reactionary. Saddam was living on borrowed time after breaking several international treaties and a failed assassination attempt on a US president, and refusing an ultimatum. The Vietnam war started as a civil war which was initiated by communists first against the French territorial government then against the Vietnamese Republic, again a reaction.
