According to a polish chap on R4 yesterday, russia has been invited to inspect all of the missile sites to ensure nothing untoward is being done, on an ongoing basis.
Some russian statements mentioned targeting these proposed sited with nuclear missiles.
As the man said, this in no way shows a polish intent to go to war, indeed polish history is full of invaders, something quoted by a russian source as the reason they (russia) are a bit huffy about the whole missile defence thing... 'cause russia is sooo besieged and have never aggressively annexed land and assets belonging for sovereign nations, oh no, not us... Using that logic you might expect the poles to be more like the russians claim to be.
Also mentioned by the polish guy was how the mask of russian diplomacy and 'partner states' is beginning to slip, revealing good old soviet suspicion and oppression.
More hot air and bombast as usual.
