International terrorism is to create an insecure collective system. But despite the different ratifications of punitive and preventive conventions against terrorism by UN security council and general assembly, the current non successful status of fighting against terrorism show that the legal-politic framework of fighting against terrorism is not efficient. In this paper it is concluded that any edition of coherent legal-politic procedure against international terrorism needs the consensus of the governments and must take into consideration the needs of the nations. So, the goal of this paper is to explain and analyze the suggested legal-politic procedures in fighting against international terrorism as a global threat accurately and scientifically. So, it is concluded that any success of global punitive and preventive procedure against terrorism needs different theoretical and practical pre conditions like the preference of reasoning cognition of terrorism against the effect of terrorism.
