Yeah. So thanks again for this excellent question. I hope to be able to answer it concisely and clearly back then, yeah, in in the early or late 1910s early 1920s Lenin and his Bolshevik government, they were confronted with nationalist movements all over the former Russian Imperial space. So there was a nationalist movement in Ukraine, in the South Caucasus, but also rising one in Central Asia. So they were confronted with what they called the nationality question, and they had to find answers. So and the Bolsheviks, despite being internationalist socialists, they chose not to ignore this but serve the wave. So the Lenin told his comrades here, we can't act against this wave of nationalism. We have to live with it and use it for our own terms. So he promised national self determination for every community. But having in mind kind of a catch. So this national self determination was always bound to being part of a socialist state. So these national republics may be, yeah, national inform, but they will be governed by elite communists chosen, of course, by Moscow. So that was the basic instrument of the Bolsheviks to manage this national diversity of their state. So they had to appreciate it in order to be able to govern at all. And yeah, now back to Putin today. In his speech, he completely ignored the historical context. Lenin couldn't act otherwise. If he would have acted otherwise, we wouldn't have any Soviet Union or Russian Federation today. So the existence of these this post Soviet order is based on this Bolshevik idea of. Of national self determination within the bounds of unified Communist Party. And of course, this was now the big idea on the top. But this big idea does not define how a real Republic like Ukraine, or Soviet Republic like Ukraine, should look like. First, the Bolshevik simply took the old Russian Imperial provinces to define what belongs to Ukraine. They took these provincial borders and then created the Ukrainian socialist Soviet Republic in 1919, but soon it was obvious that these old provincial borders would not work in the long term. So the border was revised several time, several times, and adapted to necessities following what they called economic dependencies. For instance, that when there were plants to refine sugar and fields to grow sugar beets, so this should be unified in the same Republic, not to make actually the productive base split between the republics, but then also unify certain industries within a republic. That this happened, for instance, in the Donbas at the beginning of the 1920s but now also coming to the 1950s and the question of Crimea, Crimea as a peninsula, is has climatic specific to specifics. It has a really arid climate in summertime, so it's not possible to grow any crops in on a larger scale. So the Communist Party and the state planning agency gospel then developed plans to construct a large scale canal system to irrigate the peninsula, and of course, this water would come from the Dnieper River in Ukraine, and yeah, discussion went that it's, in the end, easier to manage this large scale construction project to develop the peninsula within a Single Republic, and this was the main incentive why Crimea was then transferred in 1954 from the RSFSR to Ukraine. And as a side note, this is also what creates today problems on Crimea after 2014 Ukrainian authorities shot down all water connection to the peninsula. So after 2014 there was a large scale water scarcity on Crimea and in 2022 if I may say this, one of the first actions after the invasion war by the Russian forces was to secure the water connection near Kherson at this kakhovka dam to Crimea. And as you probably know, this dam blew up two years ago and drained the water reservoir. So now again, Crimea is on the dry you you see that this war disrupted existing economic connectivities and now led to a downturn in, let's say, in the agricultural sector, not to speak about all the industry in the Donbas that's now completely in shambles. So this war led to economic devastation in the whole region. So whoever wins this war has to deal afterwards with a landscape of ruins. Yeah.
