Not a few people believe that this is a scenario to start World War III. Ukraine is bait sent to wake Russia. Either to test how strong the Russian military is or indeed there are parties who have prepared by designing this strategy. But now the former Soviet Union, Chechnya, has declared itself to help Russia
then this becoming a world war indeed if the former USSR will be taking part as we knew that soviet is blaming the US why they are now scattered as each countries.
but i also believe that this is just a test of power and capabilities as US really wanted to gain as super power country again. I am waiting for what will be the action of china in this matter.
