In July 1997, Jeremić co-founded and became the financial manager of the Organization of Serbian Students Abroad (OSSA), the first international Serbian student association, which at the time had several thousand members. He was an active supporter of "Otpor!" ("Resistance!"), the Serbian civic youth movement that employed non-violent civil disobedience tactics against Milošević's government in the hope of spurning democratic reforms. He became even more determined to see Milošević toppled during and after NATO's bombing of Yugoslavia in the spring and summer of 1999. "This guy ... Milošević," Jeremić recalled thinking, "he has to be removed, because he’s going to get us all buried. If he stays, he’s going to get us all buried."
