You really got this one wrong, Justin.
It is never OK to meddle in another country's business. I'll say few things about Serbia and Milosevic.
As bad as Milosevic was, he was not worse then the today's leadership in Serbia. What caused people to go out on the streets to topple Milosevic was the hope that after ten years of severe economic sanctions, the US and the West will leave Serbia alone. Again, the sanctions, just like in case of Iran, is one way for the US to meddle and overthrow foreign regimes. And Serbia's was one of the color revolutions supported by Soros, which Soros is openly proud of.
The result of the color revolutions is not what people had hoped for. Serbs have now the US and West-supported leadership, they sold out literally everything in Serbia to Western companies and banks. The scenario that probably awaits Iran. So, Justin, it does matter whether the revolution is genuine or CIA-supported. In genuine revolutions people get government that works for the people, while in the CIA-caused revolutions you get a regime loyal to the foreign interests.
There was brief hope in Serbia when Kostunica came to power after Milosevic, but that was just ploy to deceive people (Zoran Djindjic was quoated several times saying that it was better that Kostunica heads the country, because people trust him more). Not before long, Kostunica was made irrelevant (the US ambassador was always very critical of him, called him a nationalist; note that anyone who puts the interests of the country first is always called nationalist).

Justin, thanks for saying it. Democrats are more dangerous than Republicans. They make it look like Obama is reaching out to Iran, while they are tearing country apart. That's what was done to Serbia, they supported criminal elements in Kosovo, and broke the country. I can only sympathize with Iranians.
