With respect, this is not a "local problem" and the error in thinking that it could be kept as such, belongs to the lunatic in the Kremlin. The time for crisis management is over when the world is being threatened with Nukes.
At this stage no one is going to capitulate or negotiate in good faith therefore trust does not exist and things must be taken at first value. If the lids are going to open make sure that yours are the first.
