Putin may be a czarist but he is not a communist.
He rebuilt all the churches destroyed during the soviet era and built new ones all over Russia. I respectfuly suggest that you dont know what you are talking about.
He is a Russian Nationalist who wants Russia to be a world power. In and of itself, I have no qualms with that. A powerful Russia can be a stabilizing influence in the world, especially in the Middle East.
I don’t think Putin is stupid enough to directly threaten NATO states.
