The FINANCIAL -- The post-communist world lost one of its greatest sons last week – a freedom fighter who devoted his life to the daunting task of cleansing Eastern Europe and Eurasia from the shackles of Soviet thinking and bureaucracy. Like Che Guevara before him, Big Kakha’s legacy transcends national borders. His crusade for liberty and human dignity took him in 2004 from Russia to Georgia, and – in the last year of his life – from Georgia to Ukraine. He was eager to help revolutionaries and reformers all over the world, not sparing his time, money and effort to instill liberal ideas and incubate liberal institutions. He did so in many different ways: through education and public advocacy, advising reform-minded presidents and opposition leaders, and – when given the opportunity to do so in his native Georgia – designing and implementing one of the most ambitious reform programs in recent history.
