WI: Belarus from 2021 to 1914

   This all assumes he stays in power after the Germans are defeated.  That could well concentrate public opinion in at least not opposing him.  However once that's out of the way you have a deeply unpopular leader in Belarus with minimal/no outside support and most people from 1914 having reasons to oppose him as well.  How much is Lukashenko's military and infrastructure totally independent of external supplies and equipment.  After all while the 1914 world can supply raw materials such as food, coal and iron ore say its not a good source for electronics, plastics or even oil probably given the limited production in 1914 and the lack of a way to ship it to Minsk.

  I also don't see an idiotic autocratic like Nicholas II accepting any idea of being what he would see as a puppet and while the Belarus forces can defeat the Germans in the short term - although their initial appearance will screw over the Russian supply lines and forces in places like Poland - I can't see him having the power to overrun most of European Russia.  If he was an actually popular democratic leader he could appeal to many of the Russian population and offer reform but while he can try that a lot of people from inside his own country are going to contradict that.  Nicholas might make some sort of deal while Germany is a clear threat but be intent on breaking/reversing it once the immediate crisis was over - just like he backpedaled on the Duma he was forced to allow after the 1905 revolution.

  Plus how would Lukashenko rule Russia?  Its facilities for control are in St Petersburg but can he, even with forces leave Minsk and all its technology and comforts?  Or does he send a subordinate to Sp Petersburg and give instructions to him.  Either way there is the danger of the person left in charge in Minsk or being sent to St Petersburg being bribed into betraying him or in the former case possibly thinking he can take over in Belarus and leave Lukashenko isolated. 

  There will definitely be huge butterflies and a lot of technological advancement while the 1914 world is going to be thrown into disorder by what they hear about the 'future'. 

  One thing Lukashenko might try is doing a deal with Germany.  Its not initially bordering him so he could end up with a larger state, with many down-timers in it who could be less unhappy with autocratic rule and Germany, as a very advanced state by 1914 standards might be better able to help supply some of the things Belarus needed.  This might have less tensions as Germany is more likely to accept Belarus as an ally as opposed to Russia which sees Belarus as a breakaway state.
