Look at the reduction in graft from arms sales due to actually having to supply the Russian army with equipment instead of embezzling and the loss of hard currency sales due to Russian procurement and the fall in the reputation of Russian arms.
Putin seems to have a firm grip on the army and security services who are the only institutions with the power to remove him, with the exception of a small cell that might decide to assassinate him. But anyone removing Putin would have to have a plan for the succession and Putin has done a very good job of suppressing the rise of any possible successor.
“”extended war has significantly reduced income from theft and graft.””
Here is an example of the level of Russian graft. In the last 15 years, Russia has centralized the space program. Roscosmos is their version of NASA. The previous leader of Roscosmos funneled so much money to himself, Russia had issues building and launching. I imagine that former leader is taking a long dirt nap.
Fortunately for the rest of the world, SpaceX has taken over launching people and supplies into space. During the President Trump administration, SpaceX was launching, testing and improving Starship almost once a month. The Hussein/Biden Regime has placed the massive government bureaucracy between SpaceX and launching. There would quite possibly be Starships orbiting the Earth by now.
