Potential Threat

Exploitation of biological weapons and microbial experiments has yet been authorized, but hereinafter any attempt to create synthetic virus and conducting biological experiments are unauthorized. Certainly, this prohibition consists of European states and especially France as well. 
50 years ago the system and France together performed one of the world biggest biological experiments in Africa over 4 years. Cameron, Nigeria and Libya were the victims of this secret project; 40 thousands of people lost their lives as a result of it. The virus is blown in the air via explosion. The mechanism of the virus was such that the patients lost weight and appetite at first and finally dead because of high fever. 
The reasons for this prohibition are not ambiguous: 
First, France and any of the other countries are unable to guarantee the national security through this weapon. 
Secondly, the only way to ensure the reliability of the Europeans or even the system's members is that none of them have the potential threat, since possible changes in the system positions or European positions cause to unleash this potential against the security of the system.
