you recall how long it took to take Bagdad right? you really think Putin thought this will be over in a week?
come on.
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.
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.
I can understand that he was lied to, and/or he miscalculated the power of his own army. But at this point it should be clear even to him it's a complete mess and they are being ridiculed by the whole world - outdated equipment, weak morale, soldiers without food, no fuel, sinking tanks. Do they really want to be humiliated by the Nordics? I really doubt so.
My take is that Finland and Sweeden will wait a bit to see how the situation develops, and if Putin starts to bark about enlarging the invasion, they will join in a blink.
