International support was also key to our success. Vice-President Kalla invited the Ambassadors of the USA, United Kingdom, Sweden, Finland, Japan, Australia, and Singapore and asked them to support the plan. "Please ask your government to approach and put pressure on the leaders of GAM who live in Sweden to enter the peace negotiations," Kalla said to those Ambassadors. "You are all in Aceh now for humanitarian reasons, helping the Acehnese after the tsunami, but you cannot be effective in your mission if the guns still smoke and food supplies are intercepted. You cannot build roads and bridges if there is no guarantee that you are not going to be kidnapped. The achievement of your mission here depends greatly on your support to enter peace negotiations and establish peace in Aceh," continued Kalla. This tactic worked very well.
The leadership of the mediator, Martti Ahtisaari, was unmistakably decisive. He never allowed either side to discuss issues other than those he provided on the agendas and itinerary. "The only agenda and vehicle we have is special autonomy, nothing else," he said. Ahtisaari was also easily able to find appropriate words to avoid the sensitivities of both sides. He had the courage to say to both sides: "Do not waste my time if you just come to my place to curse each other. You come here for a solution, not for condemnation." In addition, Ahtisaari said, "if you keep talking about the idea of independence, please leave my room and never come back. But remember, you will never get what you dream. Not in my lifetime. I will use all of my muscles to influence Europe and the world not to support you. You will never get independence."
