Was it not the defeat in the war that started the revolution and the crumbling of the empire??not to mention the crumbling Russian Empire would have far more effect on the war
being the roots of the revolution began around 1905,1906, the Parliment was dissolved returning what little power the people had to the Tsar. theTsar Abdicated in Feb of 1917. through out 1917 fighting between Communists, and Tsarist troops occur in major cities, by Nov. of 1917 the Communist held the power. it wasnt unitl March of 1918 that peace was restored with the Treaty of Brest-Litovsk
so no, the Russians were not defeated prior tot he revolution. and no the losses suffered during the war were not the cause of the Revolution. the Revolution was long in the works, the deaths, food shortages and other hardships certainly worked to enflame the problem, but they were not the cause.
I find it repulsive for you to imply that the French, British and the other allies were not doing their part to defeat the Germans during that stage of WWI. They suffered more causalities than the Germans from 1915-17. The French were suffering such loses that only the introduction of the American troops kept that country from failing.
i find it repulsive that you apparently cant read. never did i dismiss the works of the brits or french. unless of course you are so prejudiced against the Russians you link my comparison of the two fronts stalemates as an insult.
