After the war in Abkhazia, Nadareishvili was elected by fellow Georgian refugees as the head of an exile government.
In the 1990s he served at times in the Georgian parliament, continuing to draw support from refugees, to whom he helped distribute government aid.
The Forest Brothers under Dato Shengelia and the White Legion under Zurab Samushia were both allegedly associated with the Supreme Council.
[citation needed] Nadareishvili remained neutral during the Rose Revolution that ousted Eduard Shevardnadze in favor of Mikhail Saakashvili.
In 2005 he published a book ("Conspiracy Against Georgia"), which mostly includes information about ethnic cleansing and genocide of Georgian population in Abkhazia.
