If a robber invades your house and destroys 15% of it and you end up shooting them in the head, removing a 25% of their brain, disabling them, making them incapable of invading another home, then yes, the homeowner won. More importantly, everyone else won.
Like what happened to Russia after WW2, stalin's purges, the USSR's collapse. Russia is suffering a fourth round of terrible brain drain that now makes them incapable of beating jeets in space. A more retarded russia is a win for them and their neighbors when they could maintain a competent military before the invasion.
