unified message and diverse membership proved much more attractive to young activists than the deeply divided opposition parties of the time. Although they had found common ground in Otpor, the separate opposition parties were still reluctant to cooperate among themselves. Otpor's major challenge was to bring these divided groups together in preparation for the 2000 election campaign. Instead of using old methods of "bringing everyone to the table and then…trying to come up with a common strategy and goal", the original core group of Otpor founders had gathered to first find a single goal that everyone could agree upon: removing Milošević. During the presidential campaign of September 2000, Otpor launched its "Gotov je" (He's Finished!) and the "Vreme Je!" (It's Time!) campaigns, which galvanized national discontent with Milošević and eventually resulted in his defeat. Some students who led Otpor used Serbian translations of Gene Sharp's writings on nonviolent action as a theoretical basis for their campaigns. Otpor became one of the defining symbols of the anti-Milošević struggle and his subsequent overthrow. By aiming their activities at the pool of youth abstainers and other disillusioned voters, Otpor contributed to one of the biggest turnouts ever for the 24 September 2000 federal presidential elections with more than 4,77 million votes (72% of the total electorate). Persuading a large number of the traditional electorate to abandon Milošević was another one of the areas where Otpor played a key role. Milošević had in the past succeeded in persuading the public that his political opponents were traitors working for foreign interests, but in the case of Otpor, the tactic largely backfired, as the beatings and imprisonments of their members during the summer of 2000 only further cemented the decision to vote against the government in many voters' minds. Strategy and tactics Principles of the movement Otpor operated on the basis of three principles: unity, planning, and nonviolent discipline. It used the following ten strategies to achieve success: Take an offensive approach Understand the concept of "power in numbers" Develop a superior communication strategy Create the perception of a successful movement Invest in the skills and knowledge of activists Cultivate external support Induce security force defections Resist oppressionPlan B: Using Secondary Protests to Undermine Repression Zorana Smiljanic By means of decentralized leadership, education, using humor to maintain morale, and supporting members who had been arrested Use elections to trigger change Enable peaceful transition of power Tactics
