No, not territory as such. Wars were for resources; and yes, this could be territory. Roman and Persian empires went to war for, among other things, control of local trade routes. But resources could be more immaterial as well: leader's reputation, empire's reputation, diplomatic influence and so on. Many Roman-Persian wars were nothing but localized spats waged for precisely such goals: winning empire would gain reputation, which would then translate into trade concessions, but also into diplomatic and ideological influence among neighbouring countries.
So what I am saying, there is lot less difference between people and their reasoning in antiquity, middle ages and modernity than most people today like to think. We did not really advance much past apes.
RE: Pakistan, I agree with that, nothing to add.
