The people of Ukraine are pretty well split equally between those who want to be closer to the West and those who want to maintain links to Russia. There is no clear majority for either option. Interestingly, surveys suggest that a majority does support closer ties to both - a nation between east and west that wants to have its cake and eat it, and why not.
The current outbreak of violence was in reaction to an attack on the Parliament by the protesters. The resultant killing is not one-sided - police and regional politicians have been assassinated. A middle-aged woman pedestrian has been gunned down by protesters in a 'drive by'. The police have fired indiscriminately at the crowd. The armed forces are holding back.
A lot remains lost in the 'fog' of gross civil disorder, but one thing is clear - Ukraine is no Romania. This is not a case of people, police and military rising together to bring down an unwanted leader.
Under the circumstances, the amateur bunglers of the EU are the very last people I would trust in formulating any western response. Allowing Ashton to do anything at all is akin to letting the job-experience boy negotiate a new construction contract. The message from Europe's foreign ministers to the EU should be clear; shut up, butt out and wait until we tell you what to do.
