The war in Ukraine is only been 3 days. Total destruction of Ukranian Military is inevitably at this point, considering the amount of damage they are taking.
It took US 26 days of ground campaign to take Iraq, a country of desert. Not to forget the massive air campaign. Anyone expecting Russia to take second largest country in Europe with in few days are delusional.
Russians at this point are going in without a massive air campaign or artillery barrage. Even this hour, Russians have the capacity to flatten Kyiv, it's city center is already under the range of Russian artillery (Russians are less than 10 miles from city center).
Once the Ukrainian military starts collapsing, it's going to be a rapid collapse.
As long as Ukranians are willing to fight Russian soldiers
NATO will support them
A long Guerilla war will happen
Russia has developed an obsession with Conquering Ukraine .
But you cannot have Slaves in today's times
