Ahmadinejad gave an interview to al-Jazeera on January 17. The interview was summarized by al-Jazeera (in English) and is discussed by al-Jazeera commentators in this video (in English).
Judging from these two sources, he apparently avoided threats and spoke confidently about Iranian security vis-à-vis Israel. He also apparently condemned Israelis as terrorists, called for stability in Iraq, harmony in the Mideast, and resistance in Lebanon.
The interview already seems to have been twisted in the West, a common situation with his remarks. Does anyone know where to get a full transcript?
