Putin & his defense minister seem to be following in foot steps of nehru and krishna menon in 1962 . clueless people unaware of ground realities . so called kyiv seige was first hint on this.
if Russian army keeps failing to check in UA , Putin will use a tactical nuke - i think he already hinted it in his speech.
Seriously without this war nobody could have been able to see the pathetic state of Russian armed forces, even Pakistanis would have done better with those vast resources and technical know how, the way Russian armed forces are struggling is beyond comprehension.
They should first fix their planning and execution, even when they had months to secure the occupied territories but they couldn't even hold them properly.
Only saving grace they will have if they somehow able to retake newly declared borders and hold them properly, else they will have hard time recovering from this.
Have to give it to Ukraine even when having a comedian as president, they are having good planners and motivated troops, with US help they are able to get better intel and those guys taking action on intel data and utilising it properly and giving bloody noes to bigger and experienced adversary.
