It’s too much to hope for that Ukraine repulses Russia’s invasion — you have to assume that Russia’s overwhelming advantage will tell.
But the Ukrainian resistance to this point has achieved some important things. A good thread:
I think the likeliest outcome is still Russian conventional victory due to overmatch. The advances in the south are concerning. But in a country the size of Ukraine, territorial losses are acceptable so long as defenders don't suffer catastrophic defeats – defence in depth.
