Putin merely banished him to hard labor in an arctic gulag. Temps were said to not be colder than -32C. His death is an unfortunate coincidence and had nothing to do with the conditions Putin forced on him, comrade.
Considering Navalny was to be exchanged for a russian spy, I don't believe that his death was intended. His location propably was chosen because it would isolate him and prevent any contact with his handlers.
Find me any place in Russia that doesn't go below -32C in the winter. Or are you saying Russia is right to have annexed Crimea, so they can have access to warmer climates and build prisons there?
I'm going to assume that most people who reply to this article are suddenly going to doubt US intelligence because their hate for Putler trumps all common sense.
They'll refuse to engage with it just like they did when Comey and Mueller consistently failed to give them the answers they wanted. Most Democrats still believe in their hearts that the Steele dossier is real, and they'd rather annihilate the planet in nuclear fire than admit that they've spent the last decade in a self-defeating delusion.
