There are 3 main scenarios how this conflict could evolve going forward. Each of those scenario has certain probabilities of it occurring. Lets examine each one of them and their implications to the world in general:
Scenario 1 - (P:60%) #Ukarine & #Russia agree a ceasefire. Ukraine agrees to cede #Crimea and #Donbass to #Russia. #Putin withdraws #RussianArmy. #Europe over a period of time removes #sanctions. In a year, World becomes normal & everyone lives happily. Best outcome possible.
