Reorganizing Russia
USA media are seizing on the sudden announcement of a change in Russia's governing structure. They're making it sound like Medvedev is resigning in protest.
This clip clarifies what's happening:
Putin's SOTU address focused heavily on demographics. He wants to work on building Russia's future generations, strengthening culture and families. He wants Russians to produce lots of competent and civilized kids.
The reorganizing puts Medvedev in charge of foreign affairs and defense, so Putin can concentrate on internal matters. (I suspect the placement is a form of on-the-job training for Medvedev so he can be a more competent successor, but this isn't stated or implied in the available info.)
Putin is absolutely unique in the modern world, and perhaps unique in all of history. No other leader cares so deeply and comprehensively and intelligently and EFFECTIVELY about the total welfare of the nation he rules.
