Russia Ukraine war, page-2937

so can somebody correct me if im wrong, But is this basically all about Russia wanting to take over Ukraine and put a " russia " president in charge of it?

im just wondering what other views are on this, and is there any body in here who can atleast give a explanation on why Putin would even think this is reasonable ? i mean The entire Main stream media and every body's Dog is behind Ukraine .... and no im not " Defending " russia, im just curious on what other people think / why putin would do this
