Blatantly obvious he regrets it.I do wonder if he regrets this. Russia's has been exposed for what it is
He believed his own hype, thought his military was so superior to Ukraine that they would surrender within 3 days, he boasted so much about it.
I have no doubt the plan was install a puppet government like Belarus and move onto Moldova and beyond to reform the old soviet Union.
NATO shipping billions into their war effort would have knocked him for six leaving a very badly maintained armour capability at the mercy of all the high tech weapons Ukraine now found themselves getting in by the thousands every day.
Yes he must regret reducing Russia to a third rate country and he will also be very aware a top floor window could be opening for him any time soon.
