I might mention that the WTS says they do not claim to be pacifists, against all war. Here is a segment from an article specifically about that point. The WTS differentiates between pacifism and conscientious objection to war as well. This is how they get around the paradox of being neutral but supporting the destruction of the "wicked."
*** w66 7/15 p. 425 The Long-suffering of God an Eternal Blessing to Mankind ***
The long-suffering of God is not pacifism either. It may be and is accompanied by war to the death against evil or wrongdoing.

However, this refusal to pay back insult for insult does not mean Christians are to be pacifists or that they must never resort to self-defense. Christ Jesus himself will go forth to fight Jehovah’s battle of Armageddon, at the head of heavenly armies. Christians resurrected as spirit creatures will serve with him in that war. In ancient times Jehovah’s people fought at his direction and with his help. Today Christians rightfully defend the Kingdom interests, their meeting places, their right to assemble, their property, their brothers and sisters and their own persons. They do not arm in advance, in anticipation of trouble. But when attacked they may ward off blows and strike in defense, though not in offense. If attacked on public property they will call on officers of the law or withdraw, if possible, but in their homes or at their meeting places they need not retreat. They have Scriptural and legal rights to take defensive action. They are not thereby violating Jesus’ words at Matthew 5:39, for those words pertain to personal insults, not to attacks designed to do serious physical damage to one’s person.

Jehovah is no pacifist, but according to his own purpose he has righteously resorted to war against the enemies who warred against him and his people. He has never lost a battle, for his warfare is holy and righteous.
*** w51 2/1 p. 67 Why Jehovah’s Witnesses Are Not Pacifists ***
At the 1950 international assembly of Jehovah’s witnesses in Yankee Stadium, New York city, 10,000 foreign delegates were there from more than sixty other lands. Most of these had been subjected to great religious discrimination, embarrassment, hardship and inconvenience because they were obliged to clear themselves of the false charge of "extreme pacifism". An indignation meeting was held Friday afternoon, August 4, at the assembly, at which the 70,000 American delegates in the presence of these foreign brothers unanimously passed a "Regret and Protest", and at the close of the afternoon’s session a million copies of this were distributed. This 4-page paper vigorously called attention to the "Discrimination on False Charge of Pacifism" and said: "The smearing of us as extreme pacifists is without foundation and is a deliberate lie to provoke prejudice against us and this international assembly. They have done as the Scriptures prophesied, ‘framed mischief by law.’—Psalm 94:20. Extreme pacifism is not our preachment. We are not pacifists. . . . To charge that we are extreme pacifists is a lie."
As defined by Webster’s New International Dictionary
(2d edition, unabridged, of 1943) pacifism
means: "Opposition to war or to the use of military force for any purpose; especially, an attitude of mind opposing all war, emphasizing the defects of military training and cost of war, and advocating settlement of international disputes entirely by arbitration." Such pacifism not even the Bible itself can be charged with teaching, and neither can Jehovah’s witnesses, who stick most scrupulously to the Bible.
