Like the official Skripal story, which underwent numerous revisions and may get revised some more, it looks like there are some obvious holes in the evolving story concerning novichok and Russian dissident Alexei Navalny. From Craig Murray at craigmurray.com:
Once Navalny was in Berlin it was only a matter of time before it was declared that he was poisoned with Novichok. The Russophobes are delighted. This of course eliminates all vestiges of doubt about what happened to the Skripals, and proves that Russia must be isolated and sanctioned to death and we must spend untold billions on weapons and security services. We must also increase domestic surveillance, crack down on dissenting online opinion. It also proves that Donald Trump is a Russian puppet and Brexit is a Russian plot.
I should state that I have no difficulty at all with the notion that a powerful oligarch or an organ of the Russian state may have tried to assassinate Navalny. He is a minor irritant, rather more famous here than in Russia, but not being a major threat does not protect you against political assassination in Russia.
What I do have difficulty with is the notion that if Putin, or other very powerful Russian actors, wanted Navalny dead, and had attacked him while he was in Siberia, he would not be alive in Germany today. If Putin wanted him dead, he would be dead.
Let us first take the weapon of attack. One thing we know about a “Novichok” for sure is that it appears not to be very good at assassination. Poor Dawn Sturgess is the only person ever to have allegedly died from “Novichok”, accidentally according to the official narrative. “Novichok” did not kill the Skripals, the actual target. If Putin wanted Navalny dead, he would try something that works. Like a bullet to the head, or an actually deadly poison.
