Negotiation is the only way to solve the underlying problem  UN Secretary General Kofi Annan stated in 2003 “terrorism will only be defeated if we act to solve the political disputes and long-standing conflicts which generate support for it. If we do not, we shall find ourselves acting as a recruiting sergeant for the very terrorists we seek to suppress.” [1] Terrorist campaigns don't just come out of nowhere (with the exception of some single individual acts), there is a grievance behind the acts. The terrorist is trying to have this grievance dealt with and believes the best way to this end is through violence. It is clear that the easiest way to end the conflict is simply to resolve the grievance. Even when there are no negotiations the state will usually attempt to resolve some of these grievances, however doing so unilaterally will simply show that the terrorist's violence is working without getting any guarantees of an end to the violence in return. Negotiation therefore benefits both sides. It is notable that 43% of terrorist groups that have ended since 1968 have done so as a result of negotiations compared to only 7% being defeated militarily.
