Back to the USSR. East-West relations are reverting to the Cold War days. From saber-rattling, proxy wars to propaganda campaigns, few will dispute that there has been a back-slide in recent years.
But here is what I find amazing: we have already seen this movie and we know what forces are at play and what the likely outcome is. Namely, it is very difficult to maintain legitimacy as a government through a propaganda campaign. It is a highly unstable equilibrium. At any time, information can get out of the hands of the propagandists and the system will find a more stable equilibrium -- ie. leaders will be replaced. It's just a matter of time.
Right now the Kremlin is likely undergoing an intense debate on how to spin the downing of the recent Russian flight as something other than a reaction to the Russian air war in Syria. This is a heavy lift. Maybe they will succeed in this and maybe not. If so, they will have found a temporary reprieve but will no doubt find themselves encountering a similar issue in the future. The legitimacy of the Russian leadership will continually find itself teetering so long as it relies on propagandists to hold back a flood of disapproval.
Compare this system to the inherent stability of responsive governments with rule of law: healthy democracies (ie. Western democracy), responsive authoritarian systems (Singapore, China). Both these systems have release valves. In the case of democracies, elections reassert legitimacy with election cycles. In the case of responsive authoritarian systems, the government relies on surveys and technocratic leadership.
Russia has neither method of achieving stable equilibrium and so the propaganda will serve as a shaky dike holding back an ever growing force.
