War casualties have caused the fall of empires in this part of the world. WWI caused the end of Habsburg and Romanov dynasties. First usually comes the civil disobedience, in WWI the protesters burnt the records for conscription. There was already some disobedience in Belarus with workers sabotaging the trains. Expect more to follow as more body bags come home.
There will be more to follow. History teaches that famine often follows war especially during times of political and economic instability. The lunatic greens currently have power in the EU and the US. Thanks to their aggressive assault on fossil fuels, natural gas, the core ingredient of fertilizer, is expensive and scarce. Diesel fuel, which is essential to farmers, is also very expensive. Farm yields will decrease around the world. If China and India due to weather or other factors, have a poor harvest, then overt famine will occur. As it is there will be severe food shortages in Africa and parts of Asia.
The lunatic greens in the EU and US will not starve but they will be responsible for the misery, starvation and hunger wars that will come. They ought to be held responsible.
