If you mean is there just cause for war then yes, and there are many examples e.g. WWII is a just war because it was a war of Allied self defense against unjustified German aggression.

What conditions would be sufficient to make war morally justified?Is absolute pacifism a logically coherent notion?
Just Ad Bellum (resort condition)
The resort to war is justified if:
i. It has just cause e.g. self defense against unjustified aggression
ii. It is proportional - net effects of war sufficiently out weigh bad effects
iii. it is necessary - only war can bring about certain net effects compared to other alternatives e.g. diplomacy. If diplomacy could bring about the same net effects then war is not necessary or a last resort
Jus In Bellum (conduct condition)
Closely connect with Jus Ad Bellum condition, though this is controversial. Further criterion can be added for example the discrimination between combatants and non-combatants.
I have a couple friends who are pacifists, but they consider themselves to be contingent pacifists. I think what that means is that the use of force is only justified contingent with self defense (which to me sounds like a restrictive version of Just War Theory anyways)

But I am unsure whether I would want to adopt a consequentialist or non-conquestialist approach.
Just war theory is not a wholly consequentialist, e.g.necessity and discrimination requirements. Just war theory incorporates more of a deontological approach e.g. we weight the harm done to civillians more heavily than harm done to soldiers. Consequentialism would weigh these as equal in their calculations.

As has been mentioned, at face value this seems correct if we assume the positions of those who goto war, because in reality no one thinks t hey are fighting an unjust war. However, it does not mean morally speaking that a side is justified based on the populace opinion.
Legally speaking, we can still determine whether a participant in war is just or unjust. If this were not the case, e.g. both sides justified in resorting to war, then legal prosecution of war would not be possible. However, the legal framework as it now functions is heavily in need of revision (war today is not fought primarily between states).

Still does not follow that they are morally justified for doing so, if we accept the conditions of just war theory.
