the thing is they can, the whole invasion is messed up , it seems that some kind of sabotage is taking place within Russia itself - they had 8 years to prepare, they've started with bombings of ukrainians bases, then what? They were unable to do shit, they've lost thousands of soldiers, hundreds of tanks, trucks, helicopters, nothing makes sense to me
This is map of main ukrainian roads - if you have to conquer Kiev, why the fuck would you even try to go to Mariupol? THERE IS NOTHING THERE. Why you dont move all your tanks and troops from Lugansk and Donetsk to Kharkiv and then Poltava and then Kiev? and also part of the army was coming from Belarus, you can go straight to Kiev from there. Now Russian army is completely lost, they don't know what to do, its feels like Putin was really manipulated into thinking that Russian people of Ukraine are going to welcome russian army and let them go to Kiev in 2-3 days
