Yes, that's what I understand MOnica. A no fly zone would have to be policed, presumably by NATO members, and as soon as the NFZ was enforced by shooting down a Russian plane, then Russia would declare itself at war against NATO with NATO being the instigator. From what I have read from various sources, many military and political pundits think this is Putin's aim. I did hear a bit of an interesting report on R4 this morning; basically, all the Putin inner circle, the people with yachts, villas, properties in many cities, children in UK schools, wives with accounts at Harrods etc., now stand to lose a great deal, their lives now will be Russia only, not what they and their families are used to, it was described as being trapped in a rich North Korea. It is hoped they will be the ones to 'persuade' Putin, presumably with the help of CIA, MI5 types. Putin is obviously ill, he is erratic, rants for hours, and is looking very puffy about the face, maybe he is terminally ill and as far as he sees it, has nothing to lose as he tries to cement his place in history.
