Negotiation isolates those who are only interested in violence  Just as negotiations strengthen the moderates they isolate those who are most radical and interested in a violent solution. This isolation is key to actually winning a fight against groups using terrorist methods because terrorists are almost always hiding within the community. The only way to prevent these acts is therefore to encourage their community to persuade the terrorists to reject violence, or if they are not willing to change to aid the state. The need for help from the community is recognised in almost all conflicts against terrorist groups and insurgencies. The state succeeds when it gets the moderates on board, this is shown by the conflict in Iraq where the United States turned the tide against al Qaeda in the Al-Anbar Awakening. This victory was only made possible through the engagement and cooperation with local leaders who wanted an end to violence so were willing to talk to, and join with the US military if the result was likely to be security.
