They aren’t mad at all.
There’s a lot wrong with them, but insanity isn’t one of them. Putin is getting a lot of what he wants, and it seems he will get away with it. He also doesn’t strike me as a wild gambler. He will push and push as long as everything seems reasonably safe, and then he will back off when something serious gets in the way.
Some qualify “mad” as possession by the Devil: Putin is a textbook case, as majority of comrades. They may act somewhat reasonable and intelligent on the surface, but still be mad as Hell.
