That would be today. They count it from the post-Imperial Russia declaration of independence that was shortly thereafter crushed under the campaign to establish the Soviet Union.
Here is hoping that history is not on-course for a repeat performance.
My particular compliments to Ambassador (E & P) Ivane Matchavariani, who represents The Republic of Georgia in Japan, for his very fine Independence Day message as published in The Japan Times today.
(regrettably, The Japan Times does not make such messages available in their on-line edition.)
