They have rockets, hundreds of aircraft, thousands of tanks and yet the advancement is so slow. Their logistics have failed and there is clearly no proper communication. Well, eventually you win which such a force.

Take a note that US came from overseas, yet they had superior logistics. They also advanced hunderds of kilometers in week inside Irak, Russia is still quite stuck close to thr borders. They just got their fist major city.

"just got their first major city". after not even a week

also, did you notice that they rarely kill civilians? i am by no means trying to defend them, but I have the feeling (!) that this is on purpose. and this might slow down operations. for instance today, they agreed for ceasefire and a refugee corridor. that will again take days probably. We should not forget that Ukraine is the birthplace of Russian culture. Ukraine is essential to the identity of Russia. They won't just carpet bomb it and call it a day. If anything of the stuff that Putin and his professors have written is what they truly believe, then we can assume that Russia doesn't want to annihilate the Ukrainians.

lastly, ukraine is HUGE. its bigger than France. And tanks roll slowly. Still, Russia will very soon circle Kiew and then its a siege until Ukraine gives up. No matter how many weapons they get. No stuff will get in and out. Civilians will hopefully have left already so women and kids don't have to starve.

all of this is my own opinion and I might be totally wrong.
