I think I finally hit upon the solution to winning this War on Terrorism.
The US have an offical list of Terrorist Groups, but there have been pressure to remove some groups off that list. For example, there is a Ughir terrorist group that the United States have placed on that list, but that some people claim are actually are not terrorists and that the US placed the group on the list to appease China. The United States have also placed a socialist Muhjaidien terrorist group on the list, while the European Union recently removed that same group off the terrorist list. The United States was considering taking the Nepali Maoists off the List of Terrorist Groups after the Maoists signed a peace treaty and then get elected into the Nepali government, but then decided against doing so.
The list serves as an effective sanction on that group, which can harm that group but at the same time commit the United States to destroying that group in order to win the War. Many groups would likely benieft if they get removed from that list, since they no longer have to worry about the sanctions.
If the United States decide to begin 'de-classifying' certain groups, then that means the United States have to fight against less and less terrorist groups. The end result would be that the US would have an easier time destroying the few groups that it does consider 'terrorist'. Obivously, the US won't remove all Terrorist Groups from that list of Terrorist Groups, but if it removes most...it has an easier shot at destroying the few remaining groups on said list, rather than spreading its resources out.
The US could also use that list as a baraging tool, in a way of gaining more allies in this War on Terrorism. The US was able to get North Korea and Libya to cooperate by promising to remove these two nations from the List of State Sponsors of Terrorism.
