Are Jehovah's Witnesses particularly anti-violence?

One of the things I've heard about Jehovah's Witnesses is that they've been persecuted by governments for their pacifism : > They do not work in industries associated with the military, do not > serve in the armed services, and refuse national military service, > which in some countries may result in their arrest and imprisonment. > They do not salute or pledge allegiance to flags or sing national > anthems or patriotic songs. Jehovah's Witnesses see themselves as a > worldwide brotherhood that transcends national boundaries and ethnic > loyalties. Sociologist Ronald Lawson has suggested the religion's > intellectual and organizational isolation, coupled with the intense > indoctrination of adherents, rigid internal discipline and > considerable persecution, has contributed to the consistency of its > sense of urgency in its apocalyptic message. And from Persecution of Jehovah's Witnesses in the United States > Throughout the history of Jehovah's Witnesses, their beliefs, > doctrines and practices have engendered controversy and opposition > from governments, communities, and religious groups. Many Christian > denominations consider their doctrines to be heretical, and some > religious leaders have labeled Jehovah's Witnesses a cult. **Members of > the religion have also met with objection from governments for > refusing to serve in the military, particularly in times of war.** Many > individuals consider their door-to-door preaching to be intrusive. > These issues have at times led to persecution of Jehovah's Witnesses > in various countries, including the United States. Is their pacifism based on a rejection of all violence, or is it more a reflection of their beliefs about, and behaviour regarding governments?
