Withdrawing from Balakliya is a mistake IMO. It's a moderately sized town and will be impossible to evacuate. No doubt the Ukrainians will be rounding up people they consider to be pro-Russian and executing them like in Bucha.
Every few months people on here start talking about general mobilisation. It's not going to happen.So what needs to happen for Putin to take the gloves off and declare a general mobilization? A total collapse of the Kharkov front?
