No, provoke is normally a neutral word. The first three definitions (for those unfamiliar with how dictionaries work, they are ordered in use frequency) are neutral, only the 4th is the definition you and ledhed see in it. I indicated in my first response very clearly that I think the killing of 3000 people wasn't justified.
pro·voke ( P ) Pronunciation Key (pr-vk)
tr.v. pro·voked, pro·vok·ing, pro·vokes
1. To incite to anger or resentment.
2. To stir to action or feeling.
3. To give rise to; evoke: provoke laughter.
4. To bring about deliberately; induce: provoke a fight.
However, I think ledhed reacts strongly because he probably knows I don't consider the US to be innocent in the matter either - by involving itself in several violent conflicts and taking sides, it should not be surprised if it gains enemies. (EDIT: Ah, you're one post ahead of me there M-Spec.)
Even if you do read provoke in that (4th) sense, provoke is still a word that is still more suitable than justify or excuse, and as I am a lot more of a pacifist than him, I take offense to having my words twisted to make it seem like I condone the killing of 3000.
