Russia Ukraine war, page-129115

putin is slow to annouce mobilisations
he knows there is a political price to pay for sending more troops
it is also an admision of failure to be not able to get the job done with what he had

considering the size of russia compared to Ukraine the risk of Ukraine being overpowered by sheer weight of numbers is a possibility but no certainty at all
even the russians will have a point of being pushed too far by putin
