"Only way for Z to regain the territories lost is a total military and economic collapse of Russia.
Even Delusional Andy and tangs can’t see that happening."

well no .... you missed "polityical collapse" ....and also military and economic are separate and don't have to go together , although an economic collpase would initiate a military collpase .
So 3 ways and yes all three are very much all possibilities .....plus the other possibility ....that putin sees one of them approaching and decides to stop the war to avoid it so 4 all told .

That economist I posted last night said russia could (could ) run out of money in 6 months - personally I know they are in dire straights but couldn't attempt to quantify or judge the validity of the guys assessment .
Militarily may be most possible of all - cracks are appearing , morlae is terrible , equipment is wearing or getting blown up and reserves gone - relying on production now .
Another mobilisation needed - this winter won't be good for russian troops in Ukraine .
We see more instances now of russiazns killing their own men with artillery to stop retreats .
Politically ....how long will they ut up with this loser ??

and will China want this to continue or will he at some point start being persuasive with putes ? (so that world economy will get a boost and China can sell more .)

People always seem to expect whatever is happening now ....to keep happening .... often things change .... many real possibilities here and most of them are risks for russia rather than Ukraine .
