what agenda is he building and what does Alexander Dugin have to do with it.
I read a little on that person.
Dugin is more or less Putin's in-house mystic. Sort of a latter-day combination of Rasputin and Kissinger. Dugin has had an idea for a long time: combine the "best" aspects of communism, nazism, fascism, traditionalism, and ecologism. Wrap them all up in a new package that binds Eurasia together, and slap the West.
Mind you, the "best" aspects happen to be the most brutal. Dugin has been a long-time supporter of historical crimes against the Russian people like the Waffen SS's actions in the USSR as long as they serve his ideological system well.
Putin mourns the death of the Soviet Union and wants to bring it back. Unlike many charismatic leaders, he himself really doesn't have an ideology beyond hardcore nationalism and nostalgia for global power being wielded by Moscow. If you examine his policies and rhetoric closely he has had a dialogue with the Russian people: he wants to find an idea will galvanize them into political action so as to make Russia great again.
The trouble is that Putin has an ideological vacuum and he has been a friend of Dugin's. Dugin and Putin also share many of the same associates. I fear that Putin has found his new ideology in National Bolshevism. He's just trial testing to see what aspects are most compatible with the views and ambitions of the Russian people.
