In 2022 ukraine was a country that had fought sense 2014, which has had significant chunck taken over by russia ,unlike iraq, ukraine didnt have the money from oil exporting

And ukraine wasnt given heavy weapons until well after the innitial attack was blunted, specificly because it was expected for ukraine to fall (also why it took soo long for ukraine to get western fighters, pilot training started during the war )

Just the blunting of the innitial attacks meant that russias goal of repeating what happened with crimea were a failure

On paper is on paper

It all depends on what they are both actualy made of

On paper iraq was a dangerus oponent which would surely cause significant casualties

Just as on paper ukraine was going to fold instantly
