Cleopatra, you have to be very specific about Milosevic. Are you referring to "regrets" in terms of govt. influence in Serbia?
In which Vida, Aloimeh, and everyone else have already answered. Or are you referring to Milosevic in terms of war?
(against the neighboring nations).
I never understood why Montenegro separated from Serbia after a long stay. I don't know if this was U.S. influence pressuring them
to become a nation to make Serbia smaller, or if they really wanted to become sovereign. They did recognize Kosovo, so for this reason,
I'm going to assume could have been outside political pressure, unless of course Montenegrins themselves thought their land would take
a hit if they remain with Serbia because of economic problems of the time.
Historically most Montenegrins considered themselves Serbs and only a small minority considered themselves a separate ethnic group. Milo Djukanovic, who drove the independence of Montenegro, was far more nationalistic than Milosevic in the 1990s and called for tougher measures and more warfare.
So the Montenegrin flip-flop is purely a result of politics. They thought they could get by better with tourism and Western cash than in a union with Serbia. Unfortunately, they continue with this policy even while continuing to take advantage of benefits offered (in the past and still now) by Serbia.
