You have probably been reading propaganda. Russia has been clearly winning for over a year, and all indications are that time and attrition is on Russia’s side as well. This was quite obvious and clear from the start to anyone familiar with the history of wars involving Russia versus Europe; Russia has massive resources to tap into and an extremely educated population with extensive military and logistic legacy knowledge from the Soviet Union, which was the world superpower militarily in terms of land wars on the Eurasian continent. Russia is also a handful of kilometers from the frontline and capable of massive standardized domestic production of arms - Ukraine is getting a hodgepodge of expiring arms from all over the world in an uncoordinated piecemeal fashion. Of course Russia’s system of war is better. It’s also the soviet advantage in WW2, logistics and industrial production.

Pro-Ukrainian propaganda has been flooded through everywhere in the Western media world, so it’s likely all you have been exposed to. I recommend dabbling in Indian, Chinese, Middle Eastern diplomatic and news sources to get a wider picture of what actually is going on. Ukraine is never getting back Donbas or Crimea, and they will be lucky to get out of this with Kharkiv or Odessa
