I believe conflict must be reactionary, not preemptive, because a preemptive strike is just war sped up, starting a war before it's technically begun. That said, people usually rush into war out of fear; fear is the most powerful tool we have as humans.

"Humans are no strangers to war. After all, we've been fighting for as long as we can remember. War is all we know. In the past, we fought for Immulsion, we fought for country, we fought for freedom. But all that changed after E-Day. For 15 years, we've been fighting for our very survival, against inhuman, genocidal monsters. But it is a fight we cannot continue. Humanity faces extinction, unless we end this war now. We had hoped the Lightmass bombing would decimate the Locust Horde. But they survived, and they have returned stronger than ever. They've brought with them a force that can sink entire cities. Even Jacinto, our last bastion through these dark days, is now at risk. Soon, we'll have nothing left to defend. And that means we have only one option. Attack. Gears, what I ask of you now is not an easy thing, but it is necessary. If we are to survive, if we are to live long enough to see the seasons pass, our children grow, experience a time of peace that we have never known, we must now take this fight to the Locust. We will go to where they live and where they breed and we will destroy them. This is the day we take the battle to the heart of the enemy. This is the day we correct the course of human history. This is the day we ensure our survival as a species. Soldiers of the COG, my fellow Gears, go forth, and bring back the hope of humanity!"

-Chairman Prescott, leader of the COG, Gears of War 2.

THAT is what we would be justified in doing as humans.
I agree, man...WWII was necessary, but very few are. Pre-emptive war is just an abomination.
