For the following reasons, Jehovah’s Witnesses don’t go to war:

Obedience to God. The Bible says that God’s servants would “beat their swords into plowshares” and not “learn war anymore.”—Isaiah 2:4.
Obedience to Jesus. The apostle Peter was told by Jesus: “Return your sword to its place, for all those who take the sword will perish by the sword.” (Matthew 26:52) Jesus thus showed that his followers would not take up weapons of warfare.
Jesus’ disciples obey his command to be “no part of the world” by remaining strictly neutral in political matters. (John 17:16) They do not protest against military actions or interfere with those who choose to serve in the armed forces.
Love for others. Jesus commanded his disciples to “love one another.” (John 13:34, 35) They would thus form an international brotherhood in which no member would ever wage war against his brother or sister.—1 John 3:10-12.
The example of early Christians. The Encyclopedia of Religion and War states: “The earliest followers of Jesus rejected war and military service,” recognizing those practices as “incompatible with the love ethic of Jesus and the injunction to love one’s enemies.” Likewise, German theologian Peter Meinhold said of those early disciples of Jesus: “Being a Christian and a soldier was considered irreconcilable.”
Contributions to the community

Jehovah’s Witnesses are useful members of society and pose no threat to the security of the countries where they live. We respect governmental authority, in harmony with these Bible commands:

“Be in subjection to the superior authorities.”—Romans 13:1.
“Pay back, therefore, Caesar’s things to Caesar, but God’s things to God.”—Matthew 22:21.
Thus, we obey the law, pay our taxes, and cooperate with the government’s efforts to provide for the public welfare.

Why go to war when you will still die? There is no need to hurry.. Easy oh Jeje..
