Russia is decisively losing, I would end the war if I were them.
The increase in Self Propelled Artillery in Ukraine and 155 artillery shells in the last couple months is intimidating af given Ukraine has managed to survive so long without it and yet have legions of highly skilled drone operators that can spot for artillery ready to do so.
This isn't to say Ukraine can afford to fight forever but rather Russia is dismantling itself the longer it fights this war.
