Putin is waiting for Trump: the future of the war in Ukraine will be decided in the USA. With the end of the second year of the invasion, the momentum seems to be with the Russian forces.
Many of the fighters on the first front line are foreign "volunteers" from poor countries. Hundreds of thousands of Ukrainians of service age have fled the country since Russian forces invaded it on February 24, 2022. Many units are suffering from severe shortages of soldiers as the war drags on.
