>>511438093 (OP)In terms of Putin's own regime security, no. War was an excellent opportunity to consolidate total power and get rid of anyone he didn't like in the system, seperate wheat from the chaff as it were.
In terms of Russian state, yes. It's an economic black hole. They lost billions in foreign investment and deals, they made themselves into a pariah state in the eyes of European partners and completely reliant on Chinese goodwill. Putin's successors will have to build all the relationships from the ground up, with years lost in potential growth and losing markets that will have been replaced by other sources.
