On BBC American radio last night.
Khrushchev's grand daughter teaches in NYC and was reporting from Moscow.
She says people buy Putin's narative of the war being an exstential fight against NATO. His popularity has not dropped much.
Russia has more people above the age of 50, than teenagers. The average life expectancy for a Russian man is 59. The demographics speak for themselves. We all saw Putin's support evaporate when he called for mobilization and almost every draft age man with the resources fled the country. In five years, Russia will not be able to field an army half the size it now has. Russia will be a nation of old women and very old men.
In addition to this bleak projection, the educational system collapsed with the fall of the Soviet Union. There is not a generation of 30-something engineers and scientists. The bulk of Russia's technical workers are in their 50s. See the above life expectancy statistic. Russia will not have a next generation fighter jet or tank. There is no one to design and build it. The money which could have rebuilt the Russian technical schools went to build super yachts and villas in France.
The arithmetic is pretty simple. It really doesn't matter that Putin appears to be popular. Every Russian casualty, which is quickly approaching 100,000, was someone's son, brother, or father. This does not count the wounded and permanently disabled. There will be a price to pay for that.
The number of people who support Putin will diminish year by year, either from the hard learned political reality, or natural mortality.
