Interesting that the author is pointing out "Ukrainian" corruption which has actually diminished since Putin's puppet Yanukovych ruled in Ukraine--as though it is the corruption in Ukraine and not the corruption in Putin's Russia which is the real problem!
Ukraine needs to be helped to defend itself from the world's greatest aggressor so that it can then divert more of its energy from self defence towards its simultaneous fight against the corruption which was purposefully installed by the Kremlin both during Soviet and post Soviet times.  The West should be ashamed of their meagre support of Ukraine given the West's abandonment of the Budapest Memorandum. Instead of demanding that Russia--one of the most corrupt countries(actually an empire) stop its aggression in Ukraine (and other parts of the world) the author focuses on the victim's inadequacies rather than dealing with the bully who is continuing to kill, harass, slander and sabotage and economically devastate Ukraine.
