What do you men by 'turn defeat into victory in 1945"?

We are talking about 1945, right? The year that Budapest fell to the Red Army? The year that Dresden was raised? The year that the Red Army launched the Vistula-Oder Offensive which brought them to the approaches of Berlin? The year in which the Red Army saw off the last desperate gambles of the Third Reich, Operations Solstice and Spring Awakening? The year following 1944, which was the year of Stalin's Ten Blows? The year that Koenigsberg and the Heiligenbeil Pocket were taken?

The year that the Red Army took Berlin?

I'm sorry that this will sound condescending, I mean no offense (as half-hearted as that sounds). The thing is, 1945 was the year that the war ended in Europe. There WAS no turning 'defeat into victory' on the part of the Allies, because they were NOT in a state of defeat! They were on the verge of perhaps the most crushing and total victory in the history of warfare: the absolute destruction of the German Third Reich.

As per /u/selfpromoting, the process of recovery after Barbarossa was long and arduous; I don't know that I could supply a detailed account, but /u/Georgy_K_Zhukov could certainly do so.

Suffice to say, they had huge support via lend-lease, they could out produce and out man their axis foes, and by 1943 had developed an increasingly sophisticated army that could take on the Germans and win.
