Bro you have got to be a jester or something, a troll account surely... either that or you drank the entire world supply of stupid juice
You lost all hopes of othere taking you seriously as soon as you implied Putin is a democratic leader, let alone outright saying "yeah, Russia invaded 3 bordering countries part of its former empire that it has historical ideological/nationalistic goals to conquer, took a chunk of their land and put it in the hands of rebels, has been in the process of removing the soveirgnty of a 4th bordering country for 3 decades, and invaded a 5th bordering country to overthrow the government and make it a puppet state of the USSR – BUT this surely isn't at all like when Germany did the same thing with Austria, Slovakia, Czechia, and Poland, or when Italy did the same thing to Albania, Greece, and Ethiopia"
Russia already had Crimea secured from their previous invasion of Ukraine many years prior (which happened after Ukraine deposed of their Russian puppet dictator in a revolution BTW), the outbreak of the more recent stage of the war had little to do with Crimea. They have used the Donbass as a nationalistic war goal towards Ukraine for a long time, to say that it belongs to Russia because there are a lot of ethnic Russians (which is how almost any border region with a much larger country goes), and now that they've started a war with that they've declared full intent to dissolve Ukraine as a soveirgn state and incorporate it into Russia. It is not about some strategically important areas, it is about continuing Russification and making Russia "what it once was" by absorbing neighbour states. After Belarus and Ukraine, Georgia is undoubtedly next – hell, the only reason Russia isn't doing the same thing to Georgia is because they're busy getting their ass handed to them by Ukraine.
