Ukraine has been on an offensive for more than four months that has accomplished nothing other than feeding its troops into the Russian meat grinder.
This proxy war has been the biggest failure since Vietnam.
It's past time to spare the Ukrainians any more losses.
“if Russia takes Avdiivka, the war will be over.”
Without Russia occupying all of Luhansk, Donetsk, Zaporizhzhia or Kherson? None of them fully?
If Russia continues losing troops and equipment at the current rate around Avdiivka, then when and if they manage to capture it their army will be in shambles.
Avdiivka is not important to Ukraine except as another place to kill Russians.
