Compare the outcomes of the post-war era for both Germany and Russia. Russia, while bloodied and then some, is one of the victors of the war and Germany both crushed and dissected. Yet today Germany is a prosperous, modern nation whose economy, after something like a decade of slow growth, is doing quite well. It is also the end of an immigrant trail for not only folks from the middle east but also ethnic Germans as well as Jews from Russia. Russia, while more prosperous than it has been in recent years, is in large part dependent on the development of its oil resources. It remains a developing nation. Clearly Russia's victory did not bring it prosperity, at least not the type experienced in the West. It also did not bring the Soviet regime long-term stability.
