Why Ukraine hates Russia

The reason there are problems over there goes back to the early 1930's before World War 2 started.  Stalin basically starved to death millions of Ukrainians (estimates range from 2 million to 7 million) prior to World War 2 so the hatred between Russia and Ukraine isn't a recent event.  Putin is a typical tyrant and he will not stop with Ukraine.  The Russian economy is in shambles and the only way Putin can stay in power is to create a "Me against the World" society which by the way is working.  This is exactly what Hitler did in the 1930's leading up to World War 2 so it appears we are seeing a repeat of that period.  Thus the big question is will this eventually lead to World War 3?
