Could putin be worried about his own interior, but I thought manpower was no issue for Russia?
It’s not, obviously. The Kursk Pocket debacle could not be going any better for the Russians. The Donbas front is in full cascading collapse. This could be ended in a week with a blitzkrieg 200,000 man assault on Kiev from Belarus.
Why doesn’t Putin commit the reserves? My best guess is Putin is aware of the massive build up by NATO ground forces within striking distance. Putin takes this Einstein quote to heart and he must be able to respond immediately.
