Ukrainian president Oleksandr Turchynov declared yesterday in a live televised address that a full-scale operation involving the army will be launched to regain control over Eastern Ukraine. Whether it is a bluff or a real threat, which the Ukrainian government has the will and means to enforce, is yet to be seen. But today, the same Turchynov has declared that the Kiev government is not against holding a referendum in Eastern Ukraine and set a date for May 25. Meanwhile, there is talk of Kiev asking for UN peacekeepers. This all shows the insoluble mess the Ukrainian authorities have got themselves into.
