In the first year of World War One, the German army had pushed so deep into the territory of the Triple Entent and its allies that the Germans had overrun Belgium and most of Eastern France, pushing to within 20 miles of the heart of the French capital of Paris.
In the eyes of the world, a Central Powers victory on the Western Front seemed almost inevitable, and the German army (which had very quickly adapted to the new modern style of industrial warfare) seemed unbeatable. However this was changed by the First Battle of the Marne, wherein Six French Armies as well as an army of the British Expeditionary force repelled the German attackers. The German momentum was broken by the catastrophic defeat and the image of German invincibility was shattered, allowing the Triple Entente to push North East, driving the Germans away from the French capital.
The Iroquois Confederacy, an association of six linguistically related tribes in the northeastern woodlands, was a sophisticated society of some 5,500 people when the first white explorers encountered it at the beginning of the seventeenth century. The 1990 Census counted 49,038 Iroquois living in the United States, making them the country's eighth most populous Native American group. Although Iroquoian tribes own seven reservations in New York state and one in Wisconsin, the majority of the people live off the reservations. An additional 5,000 Iroquois reside in Canada, where there are two Iroquoian reservations. The people are not averse to adopting new technology when it is beneficial, but they want to maintain their own traditional identity.
In the light of your question I think it was a Russian success and the US is yet to achieve such achievements.

The Russians gain the upper hand because they were able to make the things stated above before the United States but in the end the US was able to make also such things in their own ways and successfully outwitting the USSR in economy and world power.
