No cost and no mention of Russia. Thus, the Secretary of the National Security and Defense Council of Ukraine Oleksandr Turchynov today announced that it turns out that Russia is striking the Ukrainian constitution.

Press Service of the NSDC quotes Turchinov statement:
Twenty years ago, a long “constitutional night” adopted the basic law of our state. “Ukraine is a sovereign and independent, democratic, social, legal state,” this is stated in Article 1 of the Constitution.

Having decided to go against us against war, Russia is trying not only to break through our defenses in the east, but also to strike at the Constitution of Ukraine. They want to wrest from the Ukrainian Constitution such basic concepts as “freedom”, “democracy”, “independence” and “unitarity”. But they will not succeed in depriving us of our freedom.

Recall that the declaration of freedom and democracy is made by a man who, with his own hand, signed a decree on the commencement of a punitive operation against his compatriots in the Donbas. To this day, civilians, including women, old people and children, continue to become victims of this operation. The same statement is made by a man who was at the top of the Maidan government, by taking a direct part in disrupting the Basic Law. Extreme hypocrisy, which for the authorities of Ukraine has long been the norm ...
