The idea that Putin looked weak is something only being promulgated on Western media, I have Russian and Belorussian friends and follow Russian Telegram channels and everywhere the idea of Putin, you like it or not, is that it emerged stronger, since pretty much all high ranking officers in the military stood by him and showed unity, and he managed to resolve the situation with as little bloodshed as possible. From the outside, everyone can cry whatever they want about him looking weak, but what matters is that inside of Russia there's more unity now than before, and that makes them look at themselves as stronger.
