Putin says only 10% of his military force is in Ukraine. What message is he trying to send?

A message of intimidation. It seems he has become isolated from his experienced military leaders and is listening to those close to him who tell him what he wants to hear. (Where else have we heard that recently?) As with the Russian experience in Afghanistan, the more troops you put on their soil, the more they will kill. It is the defenders advantage. They own the field.😷
