Unfortunately, Putin is far from stupid. Two stupid people working together might be safer - at least they could be controlled by their party handlers. One incredibly shrewd and absolutely unscrupulous actor (Putin was high up in the KGB, remember - those people weren't stupid) manipulating the other like a cheap marionette is a recipe for danger. It reminds me of nothing as much as the relationship between a certain German leader of the previous century and his unwitting Italian accomplice.
