I think that Putin is having to resort to this, it shows how crap it is going for him. His big bad Russian army isn't what he has bigged it up to be, save for an initial bombing blitz.
If he wasn't a nuclear threat he would have nowhere near the respect he does.
Well done the Ukrainians,hats off to each and everyone of them, they have shown not only bravery, but how to go about it with decorum given the circumstances. They are not moaning, they are not wilting, they are not asking for pity, they are just getting in with defending their homeland. It's inspirational.
Hopefully these type of assaults are a domestic and international own goal in or terms.
