sarah rainsford, bbc news, kyiv. well, i have been speaking to professor kathryn stoner, the director of the central democracy, developmentand director of the central democracy, development and the rule of law at stanford university. i asked rule of law at stanford university. iasked her what she thought the ultimate aim for president putin was. the problem with using nato as an excuse here, is that nato has not expanded since 2004, to russia's borders, it's expanded since then but not to russia's borders and there are no plans for ukraine to join. so then what's the point here, why has mr putin manufactured a crisis? and i think the answer is partly his own domestic politics and the example that ukraine sets, it is a flawed, young, raucous democracy, it has an open media, a lively civil society, and that's not what he would like to see in
