Putin took his measure and acted accordingly. They all thought Ukraine would lose quickly and now Zelenskyy is embarrassing them, which is why they keep offering him a "government in exile" while they can get back to the important business of surrendering to Iran.
Here's what's going to happen:
a) Ukraine stalls the Russian attack on Kiev. Putin will be pissed and escalate against Ukraine or Poland to cut off weapons.
b) Russian slowly grinds down Kiev and starts moving West. The Poles will panic and Putin will escalate to cut-off Western arms supplies.
There isn't any way this is not going to escalate. We can seize the initiative and decide how and then push negotiations, or we can risk uncontrolled escalation. My guess is we'll get the latter because we're governed by incompetent, corrupt morons.
I firmly believe the Russian escalation will be heavy us of thermobaric weapons inside Kiev. Less damaging to infrastructure but incredibly deadly to humans.

Statement of the Minister of Foreign Affairs of the Republic of Poland in connection with the statement by the US Secretary of State on providing airplanes to Ukraine
The authorities of the Republic of Poland, after consultations between the President and the Goverment, are ready to deploy – immediately and free of charge – all their MIG-29 jets to the Ramstein Air Base and place them at the disposal of the Government of the United States of America.
At the same time, Poland requests the United States to provide us with used aircraft with corresponding operational capabilities. Poland is ready to immediately establish the conditions of purchase of the planes.
The Polish Government also requests other NATO Allies – owners of MIG-29 jets – to act in the same vein.
You missed the other option, the one that is unfolding and predicted by WWII on the eastern front.
As Azov and almost all of the Uke army, is in the east where they have spent the last 8 years.
They are engaged by Russians and thinking they are holding them back.
But from the north and south, the salient is closing and soon they will be cut off with no air resupply. The forces cutting them off will probably bypass Kiev. Probably happened 30 times or more in WWII to the original nazis.
Azov should have read some history. I think they know and thats why they want a “humanitarian corridor” from Kharkov into western Ukraine.
Indeed. Based on how the current administration deals with opposing views here in this country, it's obvious that they have no capacity to understand the views of foreign countries. But lacking the advantage of a media conglomerate that does most of the day to day heavy lifting, they are completely clueless as to how to deal with people who are not intimidated. The entire diplomatic infrastructure of the US are primarily spectators.
