If there is a void it is created by you and Putin is quick to be attempting to fill it. You are the self appointed policeman of the world and it is a role that no one wants you in. The UN was long ago set up deal with international disputes but it has been emascalated by the false notion that if someone says no then nothing can be done.

Step back, let someoneelse take to lead before you implode
