The Saker provides a one minute video with translation of Putin explaining two years ago the Russian government’s concern that an overseas entity would use a false flag assassination within Russia in order to create an “involuntary martyr” that the Western media would use to demonize Russia.
According to this report by The Saker, http://www.globalresearch.ca/the-boris-nemtsov-assassination-russias-non-system-opposition-refuses-to-blame-the-kremlin/5434206 , the Washington-financed Russian opposition has not, as Washington hoped it would, joined the Western anti-Putin media campaign. Possibly the Washington-financed Russian NGOs have wised up from observing events in Ukraine. In place of “more democracy,” they got a Washington stooge government squandering Ukraine’s last cent on a losing war.
The most likely explanation of Nemtsov’s murder is that the CIA decided, as Nemtsov was completely marginalized as an opposition politician with 5% as against Putin’s 85%, that Nemtsov was worth more dead than alive. But the ploy, if that is what it is, has not worked inside Russia.
