There is one negative aspect to Navalny’s death: a good man has died. But there could never have been a happy ending in his fairy tale.
Otherwise, alas, things have rather improved.
The Russian regime has lost the potential opportunity to use a well-known political prisoner as bargaining material or a tool for blackmail.
The Russian opposition has an additional reason to abandon the idea of peaceful protest. Some of its representatives, acting by inertia, will go out into the streets of Russian cities to publicly express their grief, face persecution, and leave the RF.
I have an additional reason to increase my efforts in writing a book on the theory of war.
Other political regimes may throw a bit more fuel onto the fire of war with the RF (it would be good if without new mindless sanctions against those Russians who are easier to reach, but here life rather forces one to be a pessimist).
