There is a great deal of continuity in Russian history from the reign of Peter the Great until the present. There was clear discontinuity during the Bolshevik Revolution and the brief period when V. I. Lenin was in power, but then the USSR reverted to some very traditional practices in domestic and especially foreign affairs. Just as Tsars Peter the Great and Catherine the Great endeavored to modernize the country economically in order to strengthen it militarily so it would be competitive with Western Europe, so did 20th century Soviet leaders use economic modernization as a means of military strength rather than pursuing greater social justice.
There are obvious benefits to the financial and political elites for perpetuating the Cold War paradigm with Russia as the new old enemy and intelligence is only one dimension of this very complex issue. Unless the US decides what limits it needs to place on its own global reach and what perimeters it and its allies must place on Russian spheres of influence, the absurdity of the current policy will continue. Finally, the ultimate absurdity about the very serious issue of cyberspace security is that the US illegally hacking into computers and cell phones of its own citizens in violation of the Constitution (Fourth Amendment) is acceptable in the name of national security, while foreign entities - governments such as Russia and private such as WIKILEAKS- exposing corruption within the DNC is an act of war that must be punished by the most servere means possible! Moreover, US hacking and surveillance of foreign governments, political parties and espionage of foreign businesses and organizations is as acceptable as surveillance of US citizens in the name of Exceptionalism.
