But I believe they will slow down in the next coming months once their military is already nearing at their dead end. It seems for me, Putin is the suicidal one on this picture. But high likely, we will see some developments very soon. I don't think this war can go on extended period of time. Many are already suffering as well as dead from this unnecessary war.
They have a victory day parade on 9th May. Any decision regarding the war may come after that. But there are rumors that Putin may announce a general mobilization on 9th. Right now Russia has around 150,000 soldiers in Ukraine, which is not sufficient to capture large areas outside what they already control. Even in the eastern part (East Kharkiv, Donest and Lugansk), most of the gains were made by the militia of DPR and LPR, who are more knowledgeable about the terrain. Russian forces have struggled to make gains in areas which they control and are constantly losing territory (North Kharkiv, Kherson, Zaporozhia.etc).
