It does seem odd to broadcast your intentions and timeline, I must admit.
Russia on the other hand being in a temporarily controlled area of Ukraine are stuffed trying to move anything on the quiet with Ukrainians willing to film and upload details in real-time.
You do wonder sometimes if broadcasting your intentions could be a ruse to tie up Russians and encourage them to transfer troops from areas of greater interest, rather like the allies did with Calais before pushing in through Normandy..
