There is more than enough room for recriminations to go around, and neither group is innocent of abuse of the other.
The Serbs ended up with Tito after WW2, and while Tito worked with the USSR, he was not anti-American, but rather, pro-Tito.
Under his rule, serbian nationals spread throughout the former Yugoslavia to take up positions of power and authority, often using it to claim the best houses, land, and businesses.
When I was younger, I had some freinds and neighbors that were from Serbia, but from different generations.
The older generation told of the communists, and the murders of family members, of the confiscation of their farms.
They hated the communists.
And some told of the Nazis, WW2, the murders of family members, the war, fleeing to england, and then to the americas. ( Canada, then the U.S. )
They hated the Nazis, and some, the Croats.
The younger ones told of the lack of liberty, and they (or their parents ) slipping through the iron curtain to the relative freedom of the west.
They hated the USSR, but not necessarily communism, were ambivilant toward socialism.
Yet, others only knew of the old country from the stories of their parents, told many times.
To them, they were only stories, and they didn't really "hate" Nazis, Communists, Croats, Socialism, or anything.
Croatians under the Nazis killed as many Croatians as they did Serbs.
The Serbs in turn, killed as many Serbs as they did Croatians.
They both murdered Bosnians (Muslims) with equal efficiancy.
With the breakup of old Yugoslavia, and the fall of the Soviet Union, it was inevitable that there would be a blood-bath.
I knew it and said so, before it happened.
I understood the intense hatred between the Serbs and Croatians.
Likewise, that the Bosnians, often Muslims, would recieve a good portion of that fallout.
Serbian refugees from Croatia should leave it behind, and seek to settle in Serbia.
Attempting to re-settle in Croatia is tantamount to suicide, and they should know it.
They will never regain property, jobs, status or political (or any other kind of..) power in that nation.
They must simply accept that they are not and will not be accepted in that country for many generations, and let it be.
The Serbs are just being bull-headed, and will pay for it.
Consider this;
Where is the concern for the Russians that had lived in Estonia, Latvia, Poland, Ukraine, etc., etc., etc....
They too lost home, position, power, privilege, and were ostracized, and many were forced to leave what had been their home for generations.
They never became Latvians, Estonians, etc.. They remained russian, with the privileged status of being russian.
I don't hear anyone crying for them.
