In truth, Twitter is going to have a meltdown in the coming weeks. The bulk of the Ukranian army, which has been stationed on the east fighting the DPR/LPR breakaway factions since 2014, is facing total annihilation. They'll be surrounded in the Donbas kessel, cut off, and wiped out after which the Russian army will regroup and take Kiev from the south.
And all those airplanes we're sending them? The Russians will crater every useable airfield in Ukraine, leaving only NATO bases from which they can operate.
“take Kiev from the south”
Certainly possible. But maybe not as simple as you think.
It is about 800km from Mariupol to Kyiv. That is a long distance for supply lines. Ukrainian forces let the tanks pass and then hit the fuel trucks which have no armor.
The Russians are having trouble bringing in supplies 50km from Belarus to Kyiv.
