I've said this before — when human rights are denied and citizens have no opportunity to redress their grievances peacefully, it feeds terrorist propaganda that justifies violence. Likewise, when political opponents are treated like terrorists and thrown in jail, it can be a self-fulfilling prophecy. So the real path to lasting stability and progress is not less democracy; I believe it is more democracy in terms of free speech, and freedom of religion, rule of law, strong civil societies. All that has to play a part in countering violent extremism.
